Studying the effect of remapping on the 21 cm map mocks
Authors: Mokeddem Rahima , Hipolito‐Ricaldi W. S. , Zhang Jiajun 
Published: December 2022

AbstractIn cosmology, the construction of simulated mocks is very important to mimic real observations before they are available. Mocks allow, for example, to test the data analysis pipeline or to perform some forecast in an observational project. In this work, we present very preliminary results in constructing the 21 cm mocks by extending the remapping of dark matter halo catalogs. The remapping process helps to start from a given N‐body simulation catalog to construct a new N‐body catalog in another cosmology without the necessity of running an N‐body simulation each time. This allows us to get different N‐body statistics faster and in a computationally more efficient way.
Erfahrungen und Herausforderungen des Brückenrückbaus aus der Bauherrenperspektive
Authors: Erbismann Katharina , Gräb Marco 
Published: December 2022

AbstractViele Straßenbrücken in Deutschland stammen aus den 1950er‐und 1960er‐Jahren und wurden nach damaligem Stand der Technik geplant und für konservative Verkehrsprognosen bemessen. Aufgrund der enormen wirtschaftlichen Entwicklung mit einem stetig wachsenden Güter‐ und Individualverkehr wurden die geschätzten Verkehrszahlen jedoch schnell überholt. Die alten Bauwerke mit unterdimensionierten Straßenquerschnitten können die heutigen statischen und kapazitiven Anforderungen nicht dauerhaft erfüllen, weshalb die Bestandsbauwerke weichen müssen. Da ein ersatzloser Wegfall eines Verkehrsweges in der Regel keine Option ist, ist nahezu jeder Rückbau mit einem anschließenden Neubau verknüpft. Bestehende Verkehrsbeziehungen müssen während der Bauzeit aufrechterhalten werden. Der Bauherr und die zuständigen Auftragsverwaltungen haben Sorge zu tragen, dass alle rechtlichen und tatsächlichen Voraussetzungen zur Schaffung des Baurechts vorliegen und die Bauausführung sicher gelingt. Welche Herausforderungen und auch Risiken sich in diesem Prozess für die Bauherrenseite ergeben können, wird in diesem Beitrag dargestellt.
Klare Struktur, komplexes Tragwerk – Neubau Bahnhofplatz 1, Altdorf
Authors: Stalder Heinz 
Published: December 2022

AbstractIn Altdorf (CH) entstand mit dem neuen Dienstleistungsgebäude der Urner Kantonalbank, welches gleichzeitig als Bahnhofsgebäude fungiert, ein neues Zentrum für den öffentlichen Verkehr und ein Knotenpunkt für die Wirtschaft der Region. Auf engstem Raum zwischen der Kantonsstraße und den Gleisen der SBB realisiert, wird der Neubau unterschiedlichsten Anforderungen gerecht: Zugang zu den Bahnsteigen der SBB, Überdachung des Busbahnhofs und des Bahnsteigs von Gleis 1, neuer Hauptsitz der Urner Kantonalbank sowie diverser weiterer gewerblicher Mieter. Dem Projekt lag ein Wettbewerbsentwurf von Buchner Bründler Architekten und Dr. Lüchinger+Meyer Bauingenieure zugrunde, in dem das architektonische Konzept und der gestalterische Ausdruck des Gebäudes stark durch das Tragwerk geprägt werden. Auf das Minimum reduziert, gewährleistet das in der Fassadenebene außen liegende Tragwerk eine maximale Nutzungsflexibilität. In zwei der vier Stützenachsen in Gebäudelängsrichtung kommen Hängezugglieder zum Einsatz, die mit den vorgespannten Querträgern im 4.OG gekoppelt sind. So wird einerseits die Auskragung über dem Busbahnhof ermöglicht und zugleich andererseits das Erdgeschoss freigespielt. Die ebenfalls von Dr. Lüchinger+Meyer Bauingenieure geplante vollflächige Glasfassade rundet den ikonischen Entwurf ab.
Synthesis and Physical Properties of Tunable Aryl Alkyl Ionic Liquids (TAAILs) Comprising Imidazolium Cations Blocked with Methyl‐, Propyl‐ and Phenyl‐Groups at the C2 Position
Authors: Biller Harry , Strassner Thomas 
Published: December 2022

AbstractImidazolium‐based ionic liquids are very popular for different applications because of their low viscosity and melting point. However, the hydrogen atom at the C2 position of the imidazolium cation can easily be deprotonated by a base, resulting in a reactive carbene. If an inert ionic liquid is needed, it is necessary to introduce an unreactive alkyl or aryl group at the C2 position to prevent deprotonation. Tunable aryl alkyl ionic liquids (TAAILs) were first introduced by our group in 2009 and are characterized by a phenyl group at the N1 position, which offers the possibility to fine‐tune the physicochemical properties by using different electron‐donating or ‐withdrawing substituents. In this work, we present a new series of TAAILs where the C2 position is blocked by a methyl, propyl or phenyl group. For each of the blocking groups, the phenyl and three different phenyl derivatives (2‐Me, 4‐OMe, 2,4‐F2) are compared with respect to melting point, viscosity, conductivity and electrochemical window. In addition, the differences between blocked and unblocked TAAILs with regard to their electrochemical reduction potentials are investigated by quantum chemical methods.
An Insight into nd10 Metal Cyanide‐based Coordination Polymers Through ab‐initio Calculations: Electronic Properties and Optical Response

Published: December 2022

AbstractSemiconductors are essential for modern life since they are the basis of many current technologies that are related to better living standards. Some of them, characterized by the periodic assembling of metal cyanides with filled d‐shell (nd10) constitute an interesting series of cyanide‐based coordination polymers with physical properties such like anomalous anisotropic thermal expansion and quantum confinement effects related to the polymer's width that can be exploited for technological applications. Herein, the electronic structure of nd10 metal cyanide‐based systems were studied both experimentally and through Density Functional Theory. The band gap found for one‐dimensional (1D) −M−C≡N− (M=Cu, Ag, Au) and tetrahedral M−(C≡N)2 (M=Zn, Cd, Hg) systems can be attributed to Laporte‐allowed π
π* (Metal to Ligand Charge Transfer mechanism) combined with metal center (d
s,p) electronic transitions. Aurophilic bonding was found on the AuCN structure, and a new forbidden electronic transition associated to its band gap is reported. Computed effective and reduced masses from carriers revealed that carrier mobility and quantum confinement effects are greater in 1D systems.

Published: December 2022

AbstractAimsGestational diabetes mellitus (GDM) is a common medical complication during pregnancy. Endothelial dysfunction is considered an early step in the progression of atherosclerosis that may contribute to subclinical target organ damage. This meta‐analysis aimed to systemically review the existing data regarding endothelial dysfunction between women with and without GDM during pregnancy and post‐partum using flow‐mediated dilation (FMD).Materials and MethodsEligible studies (cohort and observational) published until October 2021 were identified in the MEDLINE, Scopus, Cochrane Library database and grey literature sources were searched.ResultsThe search yielded 2272 studies, of which 17 were fully reviewed and 12 studies (N = 740 pregnant women) were finally included. Pregnant women with GDM exhibited a significantly lower FMD compared to pregnant women without GDM (pooled mean difference −3.12; 95% CI −5.36 to −0.88). Moreover, in the immediate (1–6 months) post‐partum period, women with previous GDM showed lower FMD compared to healthy women without GDM history (pooled mean difference −7.52; 95% CI −9.44 to −5.59), whereas FMD did not differ in the late post‐partum period (more than 4 years).ConclusionsFlow‐mediated dilation is decreased in women with GDM during pregnancy and in the immediate post‐partum period, compared to women without GDM, indicating that the endothelial dysfunction noted during the pregnancy in those women persists in the immediate post‐partum period too.Clinical trial registrationPROSPERO CRD42021283113 (www.ClinicalTrials.gov).

Published: December 2022

AbstractVisible light‐driven photocatalysis has gained much attention due to its light‐harnessing characteristics and is extensively used in wastewater remediation. This paper presents a novel oxygen‐deficient manganese antimonate, MnSb2O6‐x, with a trirutile structure as an effective visible‐light‐driven photocatalyst for dye degradation. The synthesized samples were subjected to XRD, UV‐Vis DRS, SEM‐EDS, Raman, XPS, and PL analyses to study their physic chemical properties. The influence of sequential or single heating during the preparation method on the generation of oxygen vacancies is evaluated using UV‐Vis DRS, XPS, ESR, and Raman techniques. The oxygen‐deficient MnSb2O6 could achieve up to 85 % of MO degradation in 180 min under visible light irradiation, and its reusability up to six cycles was also investigated. In addition, the mechanism of dye degradation was supported with a scavenger test, and the degradation activities are correlated to the electron‐hole pair separation as convinced from the PL spectra. The simple and unique method of oxygen vacancy generation can inspire the development of antimonates with oxygen deficiencies, which have significant scope of application in environmental and energy conservation.
Characterizing seasonal differences in hydrological flow paths and source water contributions to alpine tundra streamflow
Authors: Kershaw Geoffrey G. L. , Wolfe Brent B. , English Michael C. 
Published: December 2022

AbstractAlpine headwaters collect larger volumes of precipitation per unit area than neighbouring lowlands, recharge regional aquifers, and generate a greater proportion of river discharge than their limited extent would suggest. Despite the importance of alpine headwaters, field observations and assessments of source water contributions to streamflow in alpine tundra settings are sparse throughout the subarctic and absent in the Taiga Cordillera ecozone specifically. As such, it remains uncertain how changes to seasonally specific hydrological processes control discharge of the larger rivers to which these alpine headwaters contribute. This study quantified variability in source water contributions and flow paths during the 2019 open water season within a Mackenzie Mountain alpine tundra basin based on measurements of stable water isotopes, specific conductivity (SPC), and water volumes during runoff generating events. During the freshet, large daily snowmelt volumes resulted in the greatest volume of streamflow, which was composed mainly of pre‐event water (~92%). As the summer progressed, evapotranspiration increased, and groundwater flow paths extended, resulting in reduced event water fractions and hydrograph amplitude, and an extended duration of streamflow response. A headwater subbasin within the larger study basin was both hydrologically and isotopically unresponsive to summer rains, and instead was characterized by a delayed hydrograph response and reduced event water fraction. Results indicate this portion of the catchment was regulated by discharge from groundwater springs capable of sustaining streamflow before snowmelt commenced and during the dry summer months. As climate change continues, greater precipitation volumes and a longer open water season will likely result in reduced runoff and stream discharge from alpine basins as greater evapotranspiration and channel bed infiltration occur. This study provides a valuable data set and observations of seasonally distinct runoff generation processes to inform prediction of changes in northern alpine tundra hydrology in response to a warming climate.
Guiding task work in the context of an emotion‐focused relationship
Authors: Goldman Rhonda , Goldstein Zoë 
Published: December 2022

AbstractIn undertaking the complex process of being an emotion‐focused therapist, one needs to strike a careful balance between providing a safe relational environment, while navigating with clients through their emotional world. In response to in‐session verbal and non‐verbal indicators, they invite clients to engage in chair work tasks designed to facilitate emotional exploration and deepening with a goal of emotional transformation. Therapists may be daunted by the prospect of introducing chair work tasks, and concerned about the impact on the relational bond. However, chair work tasks can deepen emotional exploration and shifts, and streamline the process of change. The case of Emma* will illustrate how therapists navigate the interplay between striking an empathic relationship and facilitating chair work tasks. The case will demonstrate how the therapist addresses hesitation or reluctance expressed by the client, while strengthening the bond and deepening emotional processing (*Pseudonym).

AbstractBackground and ObjectivesUnderstanding racial disparity is crucial to addressing health equity and access to care. Our study aims to examine racial differences in breast conserving surgery (BCS) utilization rates and determine how these rates have changed over time.MethodsThis retrospective cohort analysis utilized the NSQIP database to identify women diagnosed with breast cancer who underwent BCS procedures between 2008 and 2019. Racial utilization trends were analyzed using a Cochran—Armitage test and Index of Disparity analysis.ResultsIn the 12‐year period, 202 492 women underwent a breast cancer surgery, of which 47% underwent BCS. Within the BCS subgroup, oncoplastic surgery utilization increased from 3% to 10%, leading to a declining proportion of partial mastectomies: 97% to 90.0% (both p < 0.01). The racial index of disparity for overall BCS patients decreased from 7% to 6%, remained unchanged (1%) for partial mastectomies, and significantly decreased in oncoplastics (23%–7.6%).ConclusionBCS represents a mainstay option for early‐staged breast cancer interventions, this study demonstrate promising progress in decreasing the index of disparity among races and persistent racial inequalities.
Biphasic oxidation of diaquadichloro(1,10‐phenanthroline)chromium(III) by N‐bromosuccinimide and the formation of chromium(IV) and chromium(V)
Authors: Elsiddig Sulafa M. , Sulfab Yousif 
Published: December 2022

AbstractThe kinetics of oxidation of diaquadichloro(1,10‐phenanthroline)chromium(III) complex, [CrIII(phen)(H2O)2Cl2]+, by N‐bromosuccinimide (NBS) is biphasic. The first faster step involves the oxidation of Cr(III) to Cr(IV). The second slower step is due to the oxidation of Cr(IV) to Cr(V). The reaction product is isolated and characterized by electron spin resonance (ESR), IR, and elemental analysis. The chromium(V) product is consistent with the formula [CrV(phen)Cl2(O)]Br. The rate constants kf and ks, for the faster and the slower steps respectively, were obtained using an Origin 9.0 software program. Values of both kf and ks, varied linearly with [NBS] at constant reaction conditions. The effect of pH on the reaction rate is investigated over the pH (4.11–6.01) range at 25.0°C. The rate constants kf and ks increased with increasing pH. This is consistent with hydroxo forms of the chromium species being more reactive than the aqua forms. Chromium(III) complexes, more often than not, are inert. The oxidation of the Cr(III) complex to Cr(IV), most likely, proceeds by an outer sphere mechanism. Since chromium(IV) is labile the mechanism of its oxidation to chromium(V) is not certain.
Litter quality modifies soil organic carbon mineralization in an ecological restoration area
Authors: Li Yunfei , Wang Zhanjun , Shi Wanli , Yang Haotian 
Published: December 2022

AbstractSoil organic carbon (SOC) mineralization impacts the loss and accumulation of carbon (C) in crucial ways. However, it is still unclear how exactly litter quality regulates the SOC mineralization process and SOC stock. We conducted a laboratory incubation experiment under different temperatures, that is 10°C, 20°C, 30°C, and 40°C, and moisture, that is 5%, 10%, and 20% regimes, as well as a control (CK), and different litter qualities, that is, Artemisia ordosica, Caragana korshinskii, and Eragrostis minor. This was conducted in soil from a revegetated area in the Tengger Desert, northern China. We investigated the impacts of litter addition on SOC mineralization by considering the chemical properties of litter, temperature, and soil moisture, as well as the cumulative CO2‐C emissions (CCE), maximum rate (MR), potential mineralizable C (C0), priming effect (PE), temperature sensitivity (Q10), moisture sensitivity (MS), and SOC stock. Litter addition increased the CCE, MR, C0, and MS but decreased the Q10, and the effects of different litter qualities on CCE, MR, C0, MS, and Q10 differed significantly. The SOC mineralization rate increased with increasing temperature and moisture and was also accelerated by the interactions between temperature and moisture. The total C and lignin contents of litter were the key factors that governed SOC mineralization. Litter addition had a positive PE on SOC mineralization, and high‐quality litter with low C:N ratio (A. ordosica and C. korshinskii) increased the PE compared with low‐quality litter with high C:N ratio (E. minor). The PE also decreased with increasing temperature and moisture. Litter addition resulted in an acceleration of the loss of SOC mineralization, and an increase in the SOC mineralization response toward moisture but reduced the SOC mineralization response toward temperature, whereas litter quality was inversely correlated with the SOC stock. Therefore, the input of low‐quality litter will decrease the loss of mineralized SOC caused by PE and diminish the accumulation of SOC in the revegetated regions. These findings may provide a reasonable litter management model to promote the stability of soil C pool in arid revegetated areas.
Behavioral and axon histomorphometric analyses after intraneural transplantation of human skin‐ and nerve‐derived Schwann cells in nude rats
Authors: Chu Tak‐Ho , Midha Rajiv 
Published: December 2022

AbstractIntroduction/AimsWe have recently isolated and expanded skin‐derived Schwann cells (Sk‐SCs) from human skin and showed that they are largely similar to nerve‐derived Schwann cells (N‐SCs). Here, we extend our investigation into functional assessments of the nude rats that received human Sk‐SCs and N‐SCs after intraneural delivery into crushed and decellularized tibial nerve in adult nude rats.MethodsSk‐SCs, N‐SCs, dermal fibroblasts, or control culture medium was injected into the crushed and decellularized tibial nerve using in situ repeated freeze‐thaw cycles. Animals were then subjected to a ladder rung walking test, nociceptive von Frey testing, and walking gait analysis weekly. Animals were euthanized 6 weeks after surgery, gastrocnemius and soleus muscles were weighed, distal nerves were harvested, and whole semithin cross‐sections were analyzed using segmentation software.ResultsN‐SC–injected and dermal fibroblast–injected animals improved significantly at 4 to 6 weeks postinjury in nociceptive assessment compared with medium‐injected controls. Sk‐SCs recovered more rapidly in tibial functional index at 2 weeks postinjury compared with medium‐injected controls. No significant difference was observed for the ladder rung walking test or muscle weight ratio. Histologically, the number of myelinated axons was significantly higher in all cell injection groups compared with medium‐injected controls. No significant difference was observed in g ratio, axon diameter, or myelin thickness.DiscussionCell injection significantly improved axon regeneration across an in situ decellularized nerve segment. However, a more human cell–permissive animal model is required to delineate functional differences between cell types for preclinical transplantation studies.

Published: December 2022

AbstractRationaleCystic fibrosis (CF) newborn screening (NBS) algorithms in the United States vary by state. Differences in CF NBS algorithms could potentially affect the detection rate of CF newborns and lead to disparities in CF diagnosis amongst different racial and ethnic groups.ObjectivesGenerate a database of CF NBS algorithms in the United States and identify processes that may potentially lead to missed diagnoses or lead to healthcare disparities.MethodsWe sent an online survey to state and regional CF and NBS leaders about the type and threshold of immunoreactive trypsinogen (IRT) cutoff used and methods used for CFTR gene variant analysis. Follow‐up by email and phone was done to ensure a response from every state, clarify responses, and resolve discordances.ResultsThere is wide variation in the NBS algorithms employed by different states. Approximately half the states use a floating IRT cutoff, and half use a fixed IRT cutoff. CFTR variant analysis also varies widely, with two states analyzing only for the F508del variant and four states incorporating CFTR gene sequencing. The other states use CFTR variant panels ranging from 23 to 365 CFTR variants.ConclusionsCF NBS algorithms vary widely amongst the different states in the United States, which affects the ability of CF NBS to diagnose newborn infants with CF consistently and uniformly across the country and potentially may miss more infants with CF from minority populations. Our results identify an important area for quality improvement in CF NBS.
