Has Esophageal Speech Returned as an Increasingly Viable Postlaryngectomy Voice and Speech Rehabilitation Option?
Authors: Doyle Philip C. , Damrose Edward J.
Published: November 2022

Purpose:

The literature on postlaryngectomy voice and speech rehabilitation is long-standing. Although multiple rehabilitation options have existed over the years, the acquisition and use of esophageal speech (ES) has decreased significantly over the past 40 years. This reduction coincides with the increased application of tracheoesophageal puncture (TEP) voice restoration. The literature suggests that voice acquisition failures observed secondary to TEP may represent a similar phenomenon that led to ES acquisition failures.

Method:

A comprehensive review of the literature on ES and TEP voice/speech was conducted. Specific attention was directed toward information on ES and TEP speech failures. Information on pharyngoesophageal segment (PES) spasm in the context of ES and TEP voicing failures was of specific importance.

Results:

Similarities between voicing failures with both ES and TEP were identified. In order to resolve spasm in TEP speech, proactive efforts to eliminate it were undertaken, and regardless of the method used, voicing improvements were observed. These data suggest that both ES and TEP speech acquisition failures may be related to the same control mechanisms influencing the PES.

Conclusions:

The elimination of PES spasm provides evidence that justifies the reconsideration of ES. Consequently, ES may return as an increasingly viable postlaryngectomy voice and speech rehabilitation option.

Published: November 2022

To enhance the friction performance of resin‐based friction materials, five types of specimens with different polymer ether ketone (PEEK) contents were fabricated and their physiomechanical behaviours were tested and, their tribological properties were investigated using a JF150F‐II constant‐speed tester. It was found that the addition of PEEK had a positive influence on the properties of the friction materials, and sample FM‐3 (the shorthand of ‘Friction Materials‐3’, containing 2 wt% PEEK) exhibited improved friction performance with a fade ratio and recovery ratio of 8.6% and 101.1% respectively. Among all samples, FM‐4 (the shorthand of ‘Friction Materials‐4’, containing 3 wt% PEEK) had the lowest specific wear rate with a value of 0.622 × 10−7 cm3 (N·m)−1 at 350°C. The PEEK can fill the microcracks in the composite at a high temperature and can also cover the hard abrasive particles to prevent them from directly damaging the composite. The findings from this study afford a foundation for studies to further improve the properties of resin‐based friction materials.

Authors: Kharchich Fatima Zahra , Khamlichi Abdellatif
Published: November 2022

Multi-junction solar cells provide the highest efficiencies. Intense research activity is being held with the aim to increase the actual performance reached by these cells. Harvesting most of the solar spectrum and finding the optimum design variables in terms of structural parameters and carrier concentrations are the main topics being investigated by solar developers. The GaAs/GaSb based dualjunction solar cell was found suitable for the best absorption of solar spectrum. In this work, an optimization approach was applied to fix the optimal parameters of the top base layer of this structure that provide the maximum efficiency. To achieve this, a series of numerical simulations were carried out by means of Silvaco ATLAS software under standard AM1.5G spectrum where thicknesses and doping levels of the top base layer were varied. The obtained optimal structure yields a power conversion efficiency of 41.65% with open circuit voltage of 1.78V, short circuit current of 35.72mA/ cm2and fill factor of 90.16%. The performance of the GaAs/GaSb dual-junction solar cell was further improved by using sunlight concentration. A conversion power efficiency of 45.78% at 60sun light concentration was attained. It was found also that above this level of concentration ratio the detriment effect of shunt resistance dominates.
Shape control of thin deformable mirror with distributed piezoelectric sensors and actuators
Authors: Tagui Ahmed , Sanbi Mustapha
Published: November 2022

This paper presents shape control of a thin piezoelectric deformable mirror in order to compensate the form errors caused by disturbances. The finite element model describing the dynamics of the mirror was obtained by Hamilton’s principle and discretization was performed by nine nodes thin shell element according to the Kirchhoff-Love theory. The state space approach was used to generate matrices for control procedure. Because of the multivariable nature of the control problem involved in such structures and noise, the adaptive LQG-Kalman controller with multiple input-multiple output design was implemented to control the shape of the mirror. The proposed approach and related perspectives were finally discussed.

Reliable prediction in the Markov stochastic block model
Authors: Duchemin Quentin
Published: November 2022

We introduce the Markov Stochastic Block Model (MSBM): a growth model for community based networks where node attributes are assigned through a Markovian dynamic. We rely on HMMs’ literature to design prediction methods that are robust to local clustering errors. We focus specifically on the link prediction and collaborative filtering problems and we introduce a new model selection procedure to infer the number of hidden clusters in the network. Our approaches for reliable prediction in MSBMs are not algorithm-dependent in the sense that they can be applied using your favourite clustering tool. In this paper, we use a recent SDP method to infer the hidden communities and we provide theoretical guarantees. In particular, we identify the relevant signal-to-noise ratio (SNR) in our framework and we prove that the misclassification error decays exponentially fast with respect to this SNR.
Ionospheric plasma structuring in relation to auroral particle precipitation
Authors: Enengl Florine , Kotova Daria , Jin Yaqi , Clausen Lasse B.N. , Miloch Wojciech J.
Published: November 2022

Auroral particle precipitation potentially plays the main role in ionospheric plasma structuring. The impact of auroral particle precipitation on plasma structuring is investigated using multi-point measurements from scintillation receivers and all-sky cameras from Longyearbyen, Ny-Ålesund, and Hornsund on Svalbard. This provides us with the unique possibility of studying the spatial and temporal dynamics of the aurora. Here we consider three case studies to investigate how plasma structuring is related to different auroral forms. We demonstrate that plasma structuring impacting the GNSS signals is largest at the edges of auroral forms. Here we studied two stable arcs, two dynamic auroral bands, and a spiral. Specifically for arcs, we find elevated phase scintillation index values at the poleward edge of the aurora. This is observed for auroral oxygen emissions (557.7 nm) at 150 km in the ionospheric E-region. This altitude is also used as the ionospheric piercing point for the GNSS signals as the observations remain the same regardless of different satellite elevations and azimuths. Further, there may be a time delay between the temporal evolution of aurora (e.g., commencement and fading of auroral activity) and observations of elevated phase scintillation index values. The time delay could be explained by the intense influx of particles, which increases the plasma density and causes recombination to carry on longer, which may lead to a persistence of structures – a “memory effect”. High values of phase scintillation index values can be observed even shortly after strong visible aurora and can then remain significant at low intensities of the aurora.

Vergleichende Untersuchung der posturalen Kontrolle bei 20–40-Jährigen und Karate-Kaderathleten mittels eines neuromuskulären Trainingsgerätes
Authors: Osmanski-Zenk Katrin , Ningel Amelie , Tischer Thomas , Mittelmeier Wolfram
Published: November 2022

Hintergrund Die posturale Kontrolle dient dem Erhalt der aufrechten Körperhaltung und trägt zur Gleichgewichtsregulation bei. Die im höheren Alter zunehmenden neuromuskulären Defizite führen zu einer Verschlechterung der posturalen Kontrolle, die durch neuromuskuläres Training verbessert werden kann. In der Annahme, dass neuromuskuläre Defizite bereits früh auftreten, wurden die posturalen Fähigkeiten von 20–40-Jährigen untersucht. Zudem wurde der Einfluss von Leistungssport auf die posturale Kontrolle durch die Untersuchung von Karate-Kaderathleten geprüft.

Methodik Für einen Altersvergleich wurden 123 altershomogene Gesunde zwischen 20 und 40 Jahren untersucht. 24 Karate-Kaderathleten wurden mit den 20–25-jährigen Gesunden der „Normalbevölkerung“ verglichen. Zur Datenerhebung wurde ein neuromuskuläres Trainingsgerät, der Human Body Equilibrium 360 (Huber 360), verwendet.

Ergebnisse Im Altersvergleich zeigten sich für alle 7 Messungen keine signifikanten Unterschiede. Die Probanden waren zu jung, um Defizite zu erkennen. Jedoch zeigten sich einige allgemeine Erkenntnisse. Im beidbeinigen Stand war bei allen Gruppen eine signifikante Zunahme der Körperschwerpunkt (KSP) -Schwankungen nach Augenschluss zu sehen. Der Einfluss der Füßigkeit bzw. Händigkeit zeigte sich im Einbeinstand und Krafttest. Geschlechtsspezifische Unterschiede waren zu verzeichnen. Bei der Untersuchung der Karate-Kaderathleten zeigten sich verschiedene trainingsspezifische Anpassungen. So konnten Karatesportler den Wegfall der visuellen Information besser kompensieren. Karatesportler wiesen außerdem ein signifikant breiteres Gangbild und ein größeres Stabilitätsareal auf. Sportler konnten ihren KSP weiter verlagern, ohne aus dem Gleichgewicht zu geraten.

Diskussion Der Huber 360 ist als Rehabilitations- und Trainingsgerät aufgrund der geringen Trennschärfe der Tests in seinem gesamten Anwendungsspektrum nur bedingt geeignet, da signifikante Unterschiede zwischen den Gruppen schwer zu detektieren sind. Einzelne trainingsspezifische Anpassungen durch leistungsorientiertes Karatetraining sind erkennbar und unterstreichen den Einfluss des Trainings auf die posturale Kontrolle. Zusammenfassend lässt sich sagen, dass die Anwendung des Huber 360 zur Beurteilung von posturalen Fähigkeiten im Altersvergleich und bei Unterscheidung trainingsspezifischer Anpassungen einen differenzierten und selektiveren Einsatz der einzelnen Tests bedarf. Weitere Untersuchungen mit älteren Patienten mit unterschiedlichen Erkrankungen sind geplant.
Vom Nationalsozialisten zum Hitler-Erklärer: Die
autobiografischen Umdeutungen des Psychiaters Johann Recktenwald
(1882–1964)
Authors: Groß Dominik , Schmidt Mathias , Engels Pascal , Kaiser Stephanie
Published: November 2022

Ziel der Studie Im Mittelpunkt dieses Beitrags steht der bislang wenig
beleuchtete Psychiater Johann Recktenwald (1882–1964): Vom Vorwurf des
„Verbrechens gegen die Menschlichkeit“ freigesprochen, trat er
im Nachkriegsdeutschland mit einer neuropsychiatrischen Abhandlung über
Hitler an die Öffentlichkeit. Doch steht diese Selbstdarstellung eines
Hitler-kritischen Nervenarztes im Einklang mit den überlieferten
historischen Quellen? Wie war Recktenwalds Verhältnis zum NS-Regime, und
wie verhielt er sich im „Dritten Reich“ gegenüber den
ihm anvertrauten Patienten?

Methodik Der Aufsatz basiert im Wesentlichen auf z.T. erstmals
ausgewerteten Dokumenten verschiedenster Archive sowie auf Gerichtsprotokollen.
Diese werden ergänzt und abgeglichen mit den Schriften Recktenwalds und
der verfügbaren Sekundärliteratur.

Ergebnisse Recktenwald diente sich im „Dritten Reich“ in
mehrfacher Hinsicht dem NS-Regime an, trug Mitverantwortung für
zahlreiche Patientenmorde und rückte so in die Rolle eines
NS-Täters. Nach seinem Freispruch im Nachkriegsdeutschland war er
bestrebt, durch die kritische Auseinandersetzung mit der Psychopathologie
Hitlers eine persönliche Distanz zum Nationalsozialismus zu
konstruieren, die zugleich der eigenen Exkulpation diente.

Schlussfolgerung Recktenwald ist ein besonders eindrucksvolles Beispiel
für den Versuch von NS-Tätern, die eigene Rolle im
„Dritten Reich“ retrospektiv umzuschreiben – und
zugleich Spiegelbild einer Nachkriegsgesellschaft, die bereit war, derartige
biografische Umdeutungen zu akzeptieren, um der Aufarbeitung der
NS-Vergangenheit ausweichen zu können.

Predictive Value of Inflammatory Cytokines in Early Pregnancy for
Liver Dysfunction in Pregnant Women with Hepatitis B
Authors: Wang Wei , Jia Hongyan , Wang Yue , Sun Weize , Yang Can
Published: November 2022

The purpose of this study is to explore the predictive value of cytokine levels
in the first trimester of pregnancy on abnormal liver function of pregnant women
with hepatitis B in the third trimester of pregnancy. A total of 111 pregnant
women with HBV infection at 12 weeks gestation participated in the study. The
levels of IL-6, IL-8, TNF-α in peripheral blood of the patients and
liver function indexes were detected. Subsequently, the pregnant women were
followed up, and the liver function was detected at 36 weeks of gestation.
According to liver function indexes, patients were divided into normal liver
function group and abnormal liver function group to determine the correlation
between cytokines in early pregnancy and abnormal liver function in late
pregnancy. Kaplan–Meier survival curve and multivariate Cox analysis
were used to evaluate the predictive value of cytokines for liver dysfunction.
At 12 weeks of gestation, cytokine levels in the normal liver function group
were significantly lower than that in the abnormal liver function group.
Kaplan–Meier survival analysis showed that the increased IL-6 level was
associated with abnormal liver function in late pregnancy. Multivariate Cox
regression analysis revealed that IL-6 level was an independent predictor of
abnormal liver function in patients with normal liver function in the late
pregnancy. The high expression level of cytokine IL-6 at 12 weeks of pregnancy
has noteworthy predictive significance for the abnormal liver function of
hepatitis B pregnant women in third trimester of pregnancy.

Background and study aims Linked color imaging (LCI) can enhance the original color of each area and may useful to detect tumorous lesions during esophagogastroduodenoscopy. However, LCI may also enhance cancer-suspected non-cancerous regional color change. We conducted a retrospective image analysis to investigate the color characteristics of early gastric cancer (EGC) and cancer-suspected non-cancerous mucosa (CSM) in LCI.

Methods LCI images of both EGC and CSM were retrospectively collected from the database of the institution. Fifteen endoscopists individually judged each image as EGC or CSM. The color difference between the inside and outside of the lesions was measured by CIE-Lab analysis in both groups and compared.

Results A total of 245 LCI images of EGC (169) and CSM (76) were extracted and randomly lined for image collection. The test by the endoscopists showed accuracy, sensitivity, and specificity of 64.0 %, 63.7 %, and 64.0 %, respectively. Although the color difference between EGC and CSM was almost the same (12.5 vs. 12.9, not significant), each parameter of ΔL (bright: –0.3 vs. –2.7, P  < 0.001), Δa (Reddish: 7.2 vs. 9.6, P = 0.004), and Δb (Yellowish: 6.4 vs. 3.8, P  < 0.001) was significantly different in the groups. The color feature of both positive ΔL and Δb to EGC showed accuracy, sensitivity, and specificity of 54.7 %, 39.6 %, 88.2%, respectively.

Conclusions The total color difference was almost the same between EGC and CSM; however, their color tones were different on linked color imaging. Although the color characteristics of EGC had high specificity, they also had low sensitivity.

The countermovement jump, the V-cut test, the muscle thickness and the adjacent
subcutaneous fat thickness of the gastrocnemius medialis and rectus femoris are
important physiological indicators for success in basketball. The aims of this
study were to evaluate between-age-category and between-gender differences in
these indicators and examine the relationships between physical tests and
ultrasound measurements. The measurements were recorded in a sample of 131 elite
basketball players (66 males) who played in three age-categories (U14, U16, or
U18). We performed two-way analysis of covariance tests and age-adjusted partial
correlation analyses. U16 and U18 males showed better performance in the
countermovement jump and V-cut tests and lower adjacent subcutaneous fat
thickness of the gastrocnemius medialis and rectus femoris compared to the U14
males (p≤.001) and to age-category equivalent female players
(p≤.001). Comparisons between the age categories in females did not show
significant differences in any of the study variables. Adjacent subcutaneous fat
thickness of the gastrocnemius medialis explained 22.3% of the variation
for the countermovement jump result and 12.9% of the variation for the
V-cut result in males (p<.01). This study is the first to show the
association and predictive role of subcutaneous fat thickness measured by
ultrasound in physical performance of male and female elite youth basketball
players.
Don't Forget about the K-Pouch!
Authors: Shuford Rebecca , Ashburn Jean H.
Published: November 2022

The continent ileostomy (CI) was popularized by Nils Kock as a means to provide fecal continence to patients, most commonly in those with ulcerative colitis, after proctocolectomy. Although the ileal pouch-anal anastomosis (IPAA) now represents the most common method to restore continence after total proctocolectomy, CI remains a suitable option for highly selected patients who are not candidates for IPAA or have uncorrectable IPAA dysfunction but still desire fecal continence. The CI has exhibited a fascinating and marked evolution over the past several decades, from the advent of the nipple-valve to a distinct pouch design, giving the so-inclined and so-trained colorectal surgeon a technique that provides the unique patient with another option to restore continence. The CI continues to offer a means for appropriately selected patients to achieve the highest possible quality of life (QOL) and functional status after total proctocolectomy.
Surgical Management of the Armored Brain: Case Report of the Treatment of a Chronic Calcified Subdural Hematoma
Authors: Girotto André Luiz , Gago Guilherme
Published: November 2022

Calcified chronic subdural hematomas (CCSDHs) are rare entities, whose yearly incidence ranges from 1.72 to 20.6 per every 100 thousand persons. Several different approaches to their management are reported in the literature, ranging from conservative treatment to craniotomy with full removal of the neomembranes. Currently, there are no guidelines or consensus that establish the best technique. We herein report a case of symptomatic CCSDH initially drained through a burr-hole craniotomy, with no resolution of the symptoms. Later, our patient underwent a craniotomy and partial membranectomy, which resulted in full symptomatic recovery.
Design Appropriate Incision Length for Uniportal Video-Assisted Thoracoscopic Lobectomy: Take into Account Safety and Minimal Invasiveness
Authors: Shao Chen-ye , Liu Can-hui , Ren Qian-he , Liu Xiao-long , Dong Guo-hua , Yao Sheng
Published: November 2022

Background There is no criterion on the length of the uniportal video-assisted thoracoscopic surgery (UVATS) incision when performing lobectomy. We aimed to develop a nomogram to assist surgeons in designing incision length for different individuals.

Methods A cohort consisting of 290 patients were enrolled for nomogram development. Univariate and multivariate logistic regression analyses were performed to identify candidate variables among perioperative characteristics. C-index and calibration curves were utilized for evaluating the performance of the nomogram. Short-term outcomes of nomogram-predicted high-risk patients were compared between long incision group and conventional incision group.

Results Of 290 patients, 150 cases (51.7%) were performed incision extension during the surgery. Age, tumor size, and tumor location were identified as candidate variables related with intraoperative incision extension and were incorporated into the nomogram. C-index of the nomogram was 0.75 (95% confidence interval: 0.6961–0.8064), indicating the good predictive performance. Calibration curves presented good consistency between the nomogram prediction and actual observation. Of high-risk patients identified by the nomogram, the long incision group (n = 47) presented shorter duration of operation (p = 0.03), lower incidence of total complications (p = 0.01), and lower incidence of prolonged air leak (p = 0.03) compared with the conventional incision group (n = 55).

Conclusion We developed a novel nomogram for predicting the risk of intraoperative incision extension when performing uniportal video-assisted thoracoscopic lobectomy. This model has the potential to assist clinicians in designing the incision length preoperatively to ensure both safety and minimal invasiveness.

Quasi-steady imbibition of physiological liquids in paper-based microfluidic kits: Effect of shear-thinning
Authors: Asadi H. , Pourjafar-Chelikdani M. , Khabazi N. P. , Sadeghy K.
Published: November 2022

In the present work, spontaneous imbibition of shear-dependent fluids is numerically investigated in a two-layered, rectangular/fan-shaped, paper-based diagnostic kit using the modified Richards equation. It is shown that the average velocity at the test line of the kit is strongly influenced by the absorbent pad's microstructure with its contact angle playing a predominant role. Assuming that the test fluid is shear-thinning, a generalized version of the Richards equation, valid for power-law fluids, was used to investigate the effect of shear-thinning on the quasi-steady regime. The shear-thinning behavior of the test fluid is predicted to shorten the duration of the constant-velocity regime on the nitrocellulose membrane used as the test cell. By manipulating the contact angle and/or choosing appropriate microstructure for the absorbent pad, it is still possible to establish a constant velocity regime at the test line for nearly five minutes even for such fluids. A comparison between our numerical results and published numerical results obtained using simplistic theories has revealed the key role played by the transition, partially saturated zone near the advancing front during the liquid imbibition. The general conclusion is that use should preferably be made of robust models such as Richards equation for the design of lateral-flow, paper-based assays.
Shifting conflict into collaboration: peatland fires mitigation in the biosphere conservation transition zone in Sumatra, Indonesia
Authors: Ramdani Rijal , Purnomo Eko Priyo
Published: November 2022

Background Many natural resource-related conflicts throughout the globe have resulted in environmental degradation. In Sumatra, Indonesia, a conflict occurred between a timber company and the local community over peatland water sharing, causing annual peatland fires in the transition zone of biosphere conservation. Aim This study seeks to critically analyse what turning points shifted this conflict to collaboration and what roles did the convener play in the processes involved in transitioning these relationships from conflict to collaboration. Methods The data were collected through face-to-face interviews, participatory observations, document analyses, and GIS mapping carried out in 2016, 2018, and 2020. Key findings The findings show that: (1) the conflicting parties realised that there is uncertainty about the problem of peatland fires they face; (2) each party is mutually dependent, for example, concerning legitimacy and knowledge sharing of the fire mitigation; and (3) they are interested in obtaining consequential incentives, such as funding for the local community and mandatory regulation for the timber company. Conclusion We argue that the convener’s role through its legitimacy, facilitation, mandate, and persuasion is critical. Implication Without the convener’s presence, the conflict may have never been resolved and could not be turned into collaborative action.
Local gyrokinetic simulations of tokamaks with non-uniform magnetic shear
Authors: Ball Justin , Brunner Stephan
Published: November 2022

In this work, we modify the standard flux tube simulation domain to include arbitrary ion gyroradius-scale variation in the radial profile of the safety factor. To determine how to appropriately include such a modification, we add a strong ion gyroradius-scale source (inspired by electron cyclotron current drive) to the Fokker–Planck equation, then perform a multi-scale analysis that distinguishes the fast electrons driven by the source from the slow bulk thermal electrons. This allows us to systematically derive the needed changes to the gyrokinetic model. We find new terms that adjust the ion and electron parallel streaming to be along the modified field lines. These terms have been successfully implemented in a gyrokinetic code (while retaining the typical Fourier representation), which enables flux tube studies of non-monotonic safety factor profiles and the associated profile shearing. As an illustrative example, we investigate tokamaks with positive versus negative triangularity plasma shaping and find that the importance of profile shearing is not significantly affected by the change in shape.

Two-dimensional electron temperature and density profiles in the plume region of 300 W-class Hall thruster Ar plasmas were obtained using tomographically reconstructed optical emission intensity profiles combined with a collisional-radiative (CR) model. A total of 1242 lines of sight were used by rotating the thruster to apply inverse Radon transform-based tomographic reconstructions and Abel inversion. The reconstruction accuracy of the developed diagnostic system was evaluated using a priori images derived from plasma pictures, and the reconstruction error was less than 1% in the region of interest, exhibiting higher accuracy than the Abel inversion. From the Ar Hall thruster plasma, more than 12 different two-dimensional profiles of Ar I emission intensity within a spectral range of 600–1000 nm were obtained 6 mm from the exit plane of the thruster. A CR model using 31 allowed transitions at 15 different states from the ground state to the 2p
i
states was incorporated with the tomographically reconstructed emission intensity sets. Consequently, two-dimensional electron temperature and density profiles in the range of 5–18 eV and 2.0 × 1016–4.7 × 1017 m−3 were obtained, respectively, exhibiting reasonable agreement with the double Langmuir probe measurements.

We report on the first, to the best of our knowledge, simultaneous continuous-wave red, green and blue laser operations in praseodymium-doped crystalline materials. At an absorbed pump power of 4.7 W (or 10 W of incident pump power), the maximum output power was 665 mW, which included 607 nm (red), 523 nm (green) and 479 nm (blue) three wavelengths, and the optical conversion efficiency with respect to the absorbed pump power was 14.1%.

In the underwater environment, conventional hyperspectral imagers for imaging target scenes usually require stable carrying platforms for completing push sweep or complex optical components for beam splitting in long gaze imaging, which limits the system’s efficiency. In this paper, we put forward a novel underwater hyperspectral imaging (UHI) system inspired by the visual features of typical cephalopods. We designed a visual bionic lens which enlarged the chromatic blur effect to further ensure that the system obtained blur images with high discrimination of different bands. Then, chromatic blur datasets were collected underwater to complete network training for hyperspectral image reconstruction. Based on the trained model, our system only required three frames of chromatic blur images as input to effectively reconstruct spectral images of 30 bands in the working light range from 430 nm to 720 nm. The results showed that the proposed hyperspectral imaging system exhibited good spectral imaging potential. Moreover, compared with the traditional gaze imaging, when obtaining similar hyperspectral images, the data sampling rate in the proposed system was reduced by 90%, and the exposure time of required images was only about 2.1 ms, reduced by 99.98%, which can greatly expand its practical application range. This experimental study illustrates the potential of chromatic blur vision for UHI, which can provide rapid response in the recognition task of some underwater dynamic scenarios.
Expanding wildland-urban interface alters forest structure and landscape context in the northern United States

Published: November 2022

The wildland-urban interface (WUI), where housing intermingles with wildland vegetation, is the fastest-growing land use type in the United States. Given the ecological and social benefits of forest ecosystems, there is a growing need to more fully understand how such development alters the landscape context and structure of these WUI forests. In a space-for-time analysis we utilized land cover data, forest inventory plots, and housing density data over time to examine differences in forest characteristics of the northern US across three WUI change classes: (a) forest that has been in WUI housing density levels since at least 1990 (old-WUI), (b) forest where development crossed the WUI housing density threshold after 1990 (new-WUI), and (c) forest with little to no housing development (non-WUI). Of the 184 million acres of forest in the study area, 34 million acres (19%) were in old-WUI, 12 million acres (7%) were new-WUI, and 136 million acres (74%) were non-WUI. In general, as areas transitioned from non-WUI to newer WUI to older more established WUI, the forest was associated with decreased spatial integrity, increased forest-developed edges, and lower proportions of forest in the surrounding landscape. Forest in the WUI had greater carbon storage, with greater aboveground biomass, relative stand density, and more live trees per hectare than non-WUI forest, suggesting greater capacity to sequester carbon compared to non-WUI forest. At the same time, WUI forest also had significantly reduced structural diversity compared to non-WUI forest, with fewer saplings, seedlings, and dead trees per hectare. Forest that more recently crossed the WUI housing density threshold appeared to be on a trajectory towards that of old-WUI forest. These differences in forest structure across the northern US suggest reduced capacity for forest regeneration in the WUI and the potential for changes in other ecological functions.

Wheat is the most widely grown food crop, with 761 Mt produced globally in 2020. To meet the expected grain demand by mid-century, wheat breeding strategies must continue to improve upon yield-advancing physiological traits, regardless of climate change impacts. Here, the best performing doubled haploid (DH) crosses with an increased canopy photosynthesis from wheat field experiments in the literature were extrapolated to the global scale with a multi-model ensemble of process-based wheat crop models to estimate global wheat production. The DH field experiments were also used to determine a quantitative relationship between wheat production and solar radiation to estimate genetic yield potential. The multi-model ensemble projected a global annual wheat production of 1050 ± 145 Mt due to the improved canopy photosynthesis, a 37% increase, without expanding cropping area. Achieving this genetic yield potential would meet the lower estimate of the projected grain demand in 2050, albeit with considerable challenges.
Local correlations in coupled cat maps with space-time duality
Authors: Fouxon Itzhak , Gutkin Boris
Published: November 2022

We study quantum and classical correlations between local observables in perturbed coupled cat map model. In spite of fully chaotic dynamics, local correlations can be calculated explicitly due to the presence of spatiotemporal symmetry. This symmetry restricts correlations to the ‘light rays’ because the causality applies both in time and in space. We obtain detailed form of correlations of 2 and 3 sites’ observables demonstrating that exponential decay holds, generically. Furthermore, for unperturbed, pure linear, map, correlations between classical observables with a finite support exhibit superfast decay—the correlations disappear completely after a finite time.

matrices and show that spacing distribution display a range of behaviour based on the structural constraint. The spacing distribution of the ensemble of reverse circulant matrices with additional zeros is found to fall slower than exponential for larger spacing while that of symmetric circulant matrices has poisson spacings. The palindromic symmetric Toeplitz matrices on the other hand show level repulsion but the distribution is significantly different from Wigner. The behaviour of spacings for all the three ensembles clearly show the departure from universal result of Wigner distribution for real symmetric matrices. The deviation from universality continues in large n cases as well, which we study numerically.
The transfer of entanglement negativity at the onset of interactions
Authors: Wen Robin Yunfei , Kempf Achim
Published: November 2022

Quantum information, in the form of entanglement with an ancilla, can be transmitted to a third system through interaction. Here, we investigate this process of entanglement transmission perturbatively in time. Using the entanglement monotone negativity, we determine how the proclivity of an interaction to either generate, transfer or lose entanglement depends on the choice of Hamiltonians and initial states. These three proclivities are captured by Hamiltonian- and state-dependent quantities that we call negativity susceptibility, negativity transmissibility and negativity vulnerability respectively. These notions could serve, for example, as cost functions in quantum technologies such as machine-learned quantum error correction.

Solar cells cost per Watt has decreased so quickly in the last years that photovoltaic (PV) module manufacturing costs cover only a small fraction of the total costs of a PV plant. Essentially, the installation and operation costs as well as the costs for the management of starting materials are the main factors today the most important levers for total costs decrease. PV technology has advanced towards both efficiency and average energy generation increasing by light capture optimization and losses minimization. This work analyses the state-of-the-art of PV technology for terrestrial application and discusses the perspectives for future development, which aims at overwhelming limitation posed by material properties. Higher focus is given to the most promising current technology such as silicon heterojunction solar cells and on future developments based on tandem cell approaches.
