A CONVERSATION WITH MARSHALL GOLDSMITH ABOUT LIVING AN EARNED LIFE
Authors: Goldsmith Marshall , McArthur Sarah 
Published: December 2022

AbstractThis article is a conversation with Marshall Goldsmith, one of the world’s leading executive educators, coaches, and authors; and Leader to Leader co‐editor‐in‐chief Sarah McArthur, Goldsmith’s former managing editor. They discuss the principles behind Goldsmith’s new, best‐selling book The Earned Life. “We are living an earned life,” according to Goldsmith, “when the choices, risks, and effort we make in each moment align with an overarching purpose in our lives, regardless of the eventual outcome.” He continues: “Experience has taught me that there is at least one universal baseline motivation guaranteed to clarify our desire to live an earned life, and to make progress toward an overarching purpose and it is this: We want to live a life that will increase our fulfillment and minimize our regret.” Goldsmith relates the background to one of his most significant initiatives: “A number of years ago I started the 100 Coaches pay‐it‐forward community. It didn’t start as the 100 Coaches; it started as 15 Coaches. In fact, it didn’t even start as 15 Coaches, it started as an idea, a desire to connect my daily activities to a greater purpose.” He also points personal heroes: “Alan Mulally, Frances Hesselbein, Jim Yong Kim, Paul Hersey, Peter Drucker, and of course Buddha.”
LEADING IN A DIGITAL ERA WITH EQUITY, INCLUSION, AND DIVERSITY
Authors: Jules Claudy 
Published: December 2022

AbstractThe author, a partner at McKinsey & Company and former Google executive, calls for a new type of leadership and organizational governance in the evolving digital era. This means being serious and intentional about diversity, equity, and inclusion, to a greater degree than we've seen in recent years, even with the spotlight on these topics. Current reporting on metrics regarding these topics may be inadequate. “First,” Jules says, “leaders must deal with new and evolving identity categories that are becoming more common to any organization's reality.” He continues that “a second complicating issue around EID today is that it forces leaders and employees to confront and discuss what makes them uncomfortable.” Then, according to Jules, “a third challenge is answering a big question that's increasingly asked, especially if you are an investor: How diverse are the entrepreneurs you are talking to in your pipeline?” He sets out practical steps for making EID a priority. In his words, they are: Conduct an EID review; Shift mindsets and ensure an inclusive, transparent, and fair experience; Establish an EID governance structure to align leaders and reinforce mutual accountability; and Set up the right reporting and insights capabilities.

Published: December 2022

AbstractPhotothermal therapy (PTT) has been regarded as a promising strategy considering its advantages of high inherent specificity and a lower invasive burden. Since the photothermal killing of cells/bacteria showed different patterns of death depending on the varying temperature in PTT, the temperature change of PTT is vital to cell/tissue response in scientific research and clinical application. On one hand, mild PTT has received substantial attention in the treatment of cancer and soft/hard tissue repair. On the other hand, the high temperature induced by PTT is capable of antibacterial capacity, which is better than conventional antibiotic therapy with drug resistance. Herein, we summarize the recent developments in the application of temperature‐dependent photothermal biomaterials, mainly covering the temperature ranges of 40–42°C, 43–50°C, and over 50°C. We highlight the biological mechanism of PTT and the latest progress in the treatment of different diseases. Finally, we conclude by discussing the challenges and perspectives of biomaterials in addressing temperature‐orchestrated PTT. Given a deep understanding of the interaction between temperature and biology, rationally designed biomaterials with sophisticated photothermal responsiveness will benefit the outcomes of personalized PTT toward various diseases.

Published: December 2022

AbstractPolarization‐duplexing of a ytterbium‐doped fiber mode‐locked laser in all‐normal‐dispersion with an intracavity birefringent crystal is demonstrated. The laser outputs two asynchronous pulse trains with slightly different repetition rates, orthogonally crossed polarization, and colinear beams. The optical spectra are highly overlapped. A tuning of the repetition rate difference ranging from 3.7 to 8.6 kHz is realized by adjusting the birefringence in fiber. This laser offers a platform for exploring the compact fiber dual‐comb lasers with tunable repetition rate differences.
Space projectile explosion position calculation method based on curved multi‐lens array sensor
Authors: Zhang Xiaoqian , Li Hanshan 
Published: December 2022

AbstractIn the weapon test range, the space projectile explosion position parameter at the terminal trajectory is an important index to evaluate the damage performance of the projectile fuze. Due to the random distribution of the falling dispersion of the projectile, it is difficult to test the projectile explosion position in the long‐range terminal trajectory falling area. To solve this problem, this paper proposes a method for measuring the projectile explosion position based on ultra‐wide imaging with a multi‐lens array. A curved multi‐lens array optical imaging system is designed and the parameter calculation method of the optical system is presented. The relationship between the space projectile explosion position and the center of the sub‐eye lens and the relationship between the center of the sub‐eye lens and the imaging point of the image sensor is established according to the imaging principle of the optical system. The object image relations of any seven adjacent sub‐eye lenses of the curved multi‐lens array optical imaging system are combined and the calculation model of the space projectile explosion position is deduced. The experimental results verify that the designed curved multi‐lens array optical imaging system and the calculation model of the projectile explosion position proposed in this paper are reasonable.
RETRACTED: Bionic‐structure thermo‐responsive (best) hydrogels with controllable layer for high‐capacity DNA data storage

Published: December 2022

AbstractHere, a new‐rising technology (DNA storage) in which the binary digital information/data is converted into a DNA sequence composed of distinct nucleotides, providing a dense, stable, energy‐efficient, and sustainable data storage solution is studied. In principle, this technology offers substantial data density. However, the theoretical limit of DNA storage has not been achieved yet. In this study, a new DNA storage system is proposed based on hydrogels with SiO2 layer (their pore size can be regulated). The highest data density of the hydrogels is obtained to be 6.3 × 109 GB g−1. Further, by coupling them with digital polymerase chain reaction (dPCR), the recovery limit reaches five copies of DNA. Subsequently, three‐dimensional (3D) printing is used to explore the effect of macrostructures on the DNA storage capacity. Finally, bionic‐structure thermally‐responsive robust (Best) hydrogels with four different structures are developed, which achieve a data density of 1.04 × 1010 GB g−1.
Geophysical mapping of freshwater lens in Big Pine Key, Florida: Electromagnetic Induction Calibration and Application
Authors: Kiflai Michael Eyob , Whitman Dean 
Published: December 2022

AbstractGeoelectric and electromagnetic (EM) methods are rapid and non‐invasive geophysical techniques for estimating groundwater properties and characterizing the spatial and temporal variability of subsurface formations. However, to quantitatively interpret the EM data, the systematic error due to calibration problems and random error must be considered. We conducted coincident EM and electrical resistivity tomography (ERT) surveys in January and December 2018 on Big Pine Key, FL. In this study, we used vertical electrical sounding (VES) data extracted from a 220 m long ERT profile to calibrate the EM data. The inverted VES data were used as input in the EM forward model to estimate the quadrature component response. Then, the observed offset between the calculated and observed quadrature data was corrected using a multiple linear regression model. Finally, the calibrated quadrature data were converted to apparent electrical conductivity and inverted as a 2‐layer model using both the full solution and the low induction approximation. These models were used to assess the temporal and spatial variations of conductivity on a 2.2 km long E–W trending profile across the island. The calibrated apparent electrical conductivity on the profile decreased between January and December 2018, with the largest decreases in the lower elevation regions of the profile. In addition, the 2‐layer models inverted using the full solution and low induction approximation showed the depth of the freshwater interface increased by December 2018. These observations suggest the recovery of the freshwater lens due to precipitation. Based on this study, we concluded the VES at pilot locations can be used for calibration purposes and verification of the accuracy of EM measurements.

AbstractObjectiveThe goal of this study was to review the metabolic effects of fat transplantation.MethodsFat (adipose tissue [AT]) transplantation has been performed extensively for many years in the cosmetic reconstruction industry. However, not all fats are equal. White, brown, and beige AT differ in energy storage and use. Brown and beige AT consume glucose and lipids for thermogenesis and, theoretically, may provide greater metabolic benefit in transplantation. Here, the authors review the metabolic effects of AT transplantation.ResultsRemoval of subcutaneous human AT does not have beneficial metabolic effects. Most studies find no benefit from visceral AT transplantation and some studies report harmful effects. In contrast, transplantation of inguinal or subcutaneous AT in mice has positive effects. Brown AT transplant studies have variable results depending on the model but most show benefit.ConclusionsMany technical improvements have optimized fat grafting and transplantation in cosmetic surgery. Transplantation of subcutaneous AT has the potential for significant metabolic benefits, although there are few studies in humans or using human AT. Brown AT transplantation is beneficial but not readily feasible in humans thus ex vivo “beiging” may be a useful strategy. AT transplantation may provide clinical benefits in metabolic disorders, especially in the setting of lipodystrophy.
H∞$$ {H}_{\infty } $$ filtering and reduced‐order optimization methods for control of time‐delay linear systems with unknown disturbances and faults
Authors: Li Fengyuan , Zhao Dianli 
Published: December 2022

SummaryIn this paper, the problem of state and fault estimations for a class of linear time‐delay systems is studied, whose state and output are affected by delays and unknown disturbances. To solve this problem, two methods of observer design are proposed in this paper. One is a new sliding mode observer (SMO) based on proper system transformation and filter, the asymptotic stability of state and fault estimation error can be guaranteed. The second one is an adaptive sliding‐mode unknown input observer (ASMUIO), which is developed under the medium rank of the perturbation distribution matrix to estimate the disturbance simultaneously with the state and fault, and then to eliminate the disturbance effect from the estimation error systems. The conditions for the existence of the proposed SMO and ASMUIO and the strict proof of their feasibility are presented. Two numerical examples are given to illustrate the effectiveness of the new methods.

AbstractPurposeVitamin D metabolites may be protective against prostate cancer (PCa). We conducted a cross‐sectional analysis to evaluate associations between in vivo vitamin D status, genetic ancestry, and degree of apoptosis using prostatic epithelial terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) staining.Experimental designBenign and tumor epithelial punch biopsies of participants with clinically localized PCa underwent indirect TUNEL staining. Serum levels of 25 hydroxyvitamin D [25(OH)D] and 1,25 dihydroxyvitamin D were assessed immediately before radical prostatectomy; levels of prostatic 25(OH)D were obtained from the specimen once the prostate was extracted. Ancestry informative markers were used to estimate the percentage of genetic West African, Native American, and European ancestry.ResultsOne hundred twenty‐one newly diagnosed men, age 40–79, were enrolled between 2013 and 2018. Serum 25(OH)D correlated positively with both tumor (ρ = 0.17, p = 0.03), and benign (ρ = 0.16, p = 0.04) prostatic epithelial TUNEL staining. Similarly, prostatic 25(OH)D correlated positively with both tumor (ρ = 0.31, p < 0.001) and benign (ρ = 0.20, p = 0.03) epithelial TUNEL staining. Only Native American ancestry was positively correlated with tumor (ρ = 0.22, p = 0.05) and benign (ρ = 0.27, p = 0.02) TUNEL staining. In multivariate regression models, increasing quartiles of prostatic 25(OH)D (β = 0.25, p = 0.04) and Native American ancestry (β = 0.327, p = 0.004) were independently associated with tumor TUNEL staining.ConclusionsPhysiologic serum and prostatic 25(OH)D levels and Native American ancestry are positively associated with the degree of apoptosis in tumor and benign prostatic epithelium in clinically localized PCa. Vitamin D may have secondary chemoprevention benefits in preventing PCa progression in localized disease.

Published: December 2022

RationaleGas chromatography‐combustion‐isotope ratio mass spectrometry (GC/C/IRMS) is widely used for compound‐specific carbon isotopic analysis. However, current isotopic analysis systems utilize the GC IsoLink combustion reactor, and independent reduction furnaces are not implemented. Therefore, whether this limitation in furnace use affects the precision of compound‐specific carbon isotopic analysis needs to be evaluated.MethodsWe attempted to add a separate reduction furnace to the GC IsoLink interface and compared the δ13C values of n‐alkanes (including C and H elements), fatty acid methyl ester (including C, H, and O elements), caffeine (USGS61 and USGS62, including C, H, O, and N elements), and 9‐ethylcarbazole (including C, H, and N elements) before and after the addition of the reduction furnace using the GC IsoLink combustion reactor.ResultsFor n‐alkanes and fatty acid methyl esters, the δ13C differences between the measured values and their standard values were basically falling within 0.5‰ whether or not an independent reduction furnace was added. However, for the nitrogen‐containing compounds (caffeine and 9‐ethylcarbazole), the δ13C differences between the measured values and their standard values were much larger without an independent reduction furnace (1.0–3.71‰ for USGS61, 1.78–2.19‰ for USGS62, and 0.39–1.13‰ for 9‐ethylcarbazole) than with a reduction furnace (−0.31–0.68‰ for USGS61, −0.44–0.06‰ for USGS62, and −0.04–0.25‰ for 9‐ethylcarbazole).ConclusionsThe addition of an independent reduction furnace had no significant effect on the δ13C of n‐alkanes and fatty acid methyl esters, but it had a significant effect on the δ13C of nitrogen‐containing compounds. It is suggested that GC IsoLink needs an independent reduction furnace to effectively eliminate the interference of NOx on CO2 isotopic determination to improve the accuracy of δ13C for nitrogen‐containing compounds.
Rapid characterization of isotopic purity of deuterium‐labeled organic compounds and monitoring of hydrogen–deuterium exchange reaction using electrospray ionization‐high‐resolution mass spectrometry

Published: December 2022

RationaleDeuterium‐labeled organic compounds, reagents, and drugs are widely used in many scientific research fields. Isotopic purity as the feature parameter of deuterated compounds is of great importance. In this article, we used electrospray ionization with high‐resolution mass spectrometry (ESI‐HRMS) to study isotopic purity of deuterium‐labeled organic compounds based on assigning and distinguishing the corresponding H/D (hydrogen–deuterium) isotopolog ions of deuterated compounds.MethodsWe systematically considered the specific requirements of accuracy and resolution of ESI‐HRMS when measuring isotopic purity and demonstrated some actual cases using ESI‐HRMS and ultraperformance liquid chromatography (UPLC)‐HRMS. Meanwhile, ESI‐HRMS/MS of deuterated compounds was performed to obtain more information on deuterium‐labeled position characterization.ResultsTwo isotopic purity calculation methods based on the relative abundance in ESI‐HRMS and UPLC‐HRMS of H/D isotopolog ions (D0–Dn) were compared, which gave consistent isotopic purity values and were in good agreement with the certified isotopic purity values. We further studied and monitored the H/D exchange reaction of ethyl 3‐(4‐bromophenyl)‐3‐oxopropanoate (EBPO) by evaluating the dynamic isotopic purity changes in EBPO‐D2 in the H/D exchange reaction in situ.ConclusionThe isotopic purity characterization methods using ESI‐HRMS discussed in this article have some outstanding advantages: rapid, highly sensitive, very low sample consumption (even below nanogram level), and deuterated solvent‐free. Thus, this low‐impact analytical method requires less time and is cost effective and might have good application potential for in‐situ isotopic purity analysis and for monitoring the H/D exchange reactions.
A review of path following control strategies for autonomous robotic vehicles: Theory, simulations, and experiments

Published: December 2022

AbstractThis article presents an in‐depth review of path following control strategies that are applicable to a wide range class of marine, ground, and aerial autonomous robotic vehicles. From a control system standpoint, path following can be formulated as the problem of stabilizing a path following error system that describes the dynamics of position and possibly orientation errors of a vehicle with respect to a path, with the errors defined in an appropriate reference frame. In spite of the large variety of path following methods described in the literature we show that, in principle, most of them can be categorized in two groups: stabilization of the path following error system expressed either in the vehicle's body frame or in a frame attached to a “reference point” moving along the path, such as a Frenet‐Serret (F‐S) frame or a Parallel Transport (P‐T) frame. With this observation, we provide a unified formulation that is simple but general enough to cover many methods available in the literature. We then discuss the advantages and disadvantages of each method, comparing them from the design and implementation standpoint. We further show experimental results of the path following methods obtained from field trials testing with under‐actuated and over‐actuated autonomous marine vehicles. In addition, we introduce open‐source Matlab and Gazebo/ROS simulation toolboxes that are helpful in testing path following methods before their integration in the combined guidance, navigation, and control systems of autonomous vehicles.
Einsatz vom duroplastischen Spaltausgleichsmaterial DIAMANT MM1018 in vorgespannten geschraubten Verbindungen

Published: December 2022

AbstractIm Stahlbau werden Schraubverbindungen entweder aus Gründen der Tragfähigkeit oder der Gebrauchstauglichkeit vorgespannt. Ein‐ und mehrschnittige Verbindungen in Brücken, Funkmasten und Turmbauwerken von Windenergieanlagen gehören zu den typischen Einsatzgebieten. Eine Spaltbildung, hervorgerufen durch fertigungs‐ und montagebedingte Imperfektionen, stellt ein Risiko z. B. für das kontrollierte Aufbringen des erforderlichen Vorspannkraftniveaus sowie zur Vermeidung von Spaltkorrosion dar. Dies kann die Tragfähigkeit sowie die Dauerhaftigkeit der Verbindung erheblich beeinträchtigen und sogar zu einem vorzeitigen Versagen führen. Die Spaltbildung ist daher auf ein Minimum zu begrenzen, wobei DIN EN 1090‐2 dazu Maßnahmen wie z. B. den Einsatz von Futterblechen vorsieht. Eine mögliche Alternative für den Ausgleich von Spalten stellen Zweikomponenten‐Reaktionsharzsysteme auf Epoxidharzbasis dar, die zur Verbesserung der mechanischen Eigenschaften mit speziellen metallischen Werkstoffen gefüllt sind. Im Rahmen des ZIM‐Kooperationsprojekts „Bri‐San‐T – DuroFüllSta“ wurden systematische Untersuchungen zum Einsatz des duroplastischen Spaltausgleichsmaterials MM1018 der Firma Diamant Polymer GmbH in vorgespannten geschraubten Verbindungen durchgeführt. Im vorliegenden Beitrag werden die experimentell bestimmten Haftreibungszahlen sowie die zu erwartenden Vorspannkraftverluste vorgestellt.
Digitally fabricated weak interfaces to reduce minimum reinforcement in concrete structures
Authors: Bischof Patrick , Mata‐Falcón Jaime , Ammann Rebecca , Näsbom Andreas , Kaufmann Walter 
Published: December 2022

AbstractCrack initiators in reinforced concrete structures can facilitate fulfilling the serviceability requirements. They can be used as a design parameter to diminish the minimum reinforcement for members subject to imposed deformation and exposed to the environment as they reduce the crack spacing and width when arranged close enough. While crack initiators in conventional concrete construction are cumbersome to provide (e.g., by construction joints or taperings), they are inherent to layered extrusion processes with digital fabrication technologies: the tensile strength is typically reduced locally in interfaces between layers. Rather than trying to avoid these weak interfaces, this paper discusses the potential of taking advantage of them to act as crack initiators reducing the minimum reinforcement content. A tension chord‐based model is developed to (i) account for the local strength reduction and (ii) predict the effect of weak interfaces on the expected crack spacing and width. As a key finding, the model predicts a reduction of the required minimum reinforcement ratio proportional to the locally decreased concrete tensile strength for a specified maximum crack width requirement under imposed deformations. An experimental campaign on five layered and three reference tension ties confirmed the clearly positive impact of weak interfaces on crack spacings and widths.
