AbstractP2‐type layered Ni–Mn‐based oxides are vital cathode materials for sodium‐ion batteries (SIBs) due to their high discharge capacity and working voltage. However, they suffer from the detrimental P2 → O2 phase transition induced by the O2−−O2− electrostatic repulsion upon high‐voltage charge, which leads to rapid capacity fade. Herein, we construct a P2‐type Ni–Mn‐based layered oxide cathode with a core‐shell structure (labeled as NM–Mg–CS). The P2‐Na0.67[Ni0.25Mn0.75]O2 (NM) core is enclosed by the robust P2‐Na0.67[Ni0.21Mn0.71Mg0.08]O2 (NM–Mg) shell. The NM–Mg–CS exhibits the phase‐transition‐free character with mitigated volume change because the confinement effect of shell is conductive to inhibit the irreversible phase transition of the core material. As a result, it drives a high capacity retention of 81% after 1000 cycles at 5 C with an initial capacity of 78 mA h/g. And the full cell with the NM–Mg–CS cathode and hard carbon anode delivers stable capacities over 250 cycles. The successful construction of the core‐shell structure in P2‐type layered oxides sheds light on the development of high‐capacity and long‐life cathode materials for SIBs.

Published: August 2024

AbstractIn the past decade, molybdenum ditelluride (MoTe2) has received significant attention from the scientific community due to its structural features and unique properties originate from them. In the current review, the properties, various preparation approaches, and versatile applications of MoTe2 are presented. The review provides a brief update on the state of our fundamental understanding of MoTe2 material and also discusses the issues that need to be resolved. To introduce MoTe2, we briefly summarize its structural, optoelectronic, magnetic, and mechanical properties in the beginning. Then, different preparation methods of MoTe2, such as exfoliation, laser treatment, deposition, hydrothermal, microwave, and molecular beam epitaxy, are included. The excellent electrical conductivity, strong optical activity, tunable bandgap, high sensitivity, and impressive stability make it an ideal contender for different applications, including energy storage, catalysis, sensors, solar cells, photodetectors, and transistors. The performance of MoTe2 in these applications is systematically introduced along with mechanistic insights. At the end of the article, the challenges and possible future directions are highlighted to further modify MoTe2 material for the numerous functionalities. Therefore, the availability of different phases and layer structures implies a potential for MoTe2 to lead an era of two‐dimensional materials that began from the exfoliation of graphene.

Published: August 2024

AbstractThe utilization of single atoms (SAs) as trifunctional electrocatalyst for nitrogen reduction, oxygen reduction, and oxygen evolution reactions (NRR, ORR, and OER) is still a formidable challenge. Herein, we devise one‐pot synthesized palladium SAs stabilized on nitrogen‐doped carbon palladium SA electrocatalyst (Pd‐SA/NC) as efficient trifunctional electrocatalyst for NRR, ORR, and OER. Pd‐SA/NC performs a robust catalytic activity toward NRR with faradaic efficiency of 22.5% at −0.25 V versus reversible hydrogen electrode (RHE), and the relative Pd utilization efficiency is enhanced by 17‐fold than Pd‐NP/NC. In addition, the half‐wave potential reaches 0.876 V versus RHE, amounting to a 58‐time higher mass activity than commercial Pt/C. Moreover, the overpotential at 10 mA cm−2 is as low as 287 mV for Pd‐SA/NC, outperforming the commercial IrO2 by 360 times in turnover frequency at 1.6 V versus RHE. Accordingly, the assembled rechargeable zinc‐air battery (ZAB) achieves a maximum power density of 170 mW cm−2, boosted by 2.3 times than Pt/C–IrO2. Two constructed ZABs efficiently power the NRR‐OER system to electrochemically generate ammonia implying its superior trifunctionality.
Agency and Register in Translanguaging: Middle School Bilingual Learners Engaging in Social Studies Inquiry

Published: August 2024

AbstractWe report on U.S. middle school Arabic‐speaking students who were agentive in translanguaging for disciplinary learning during social studies inquiry and suggest specific ways that students' academic learning and bilingual development can be supported through translanguaging in the context of English‐dominant classrooms. We engaged in design‐based research with teachers and students over five investigations and refined our mediating processes as we encountered challenges in supporting translanguaging in this context. Analysis of video records showed that for learners to be agentive in talking about subject matter concepts, they needed register development—not only in English but also through translanguaging. Bilingual inquiry curriculum materials and encouragement are not enough; interaction with others who can discuss disciplinary concepts through translanguaging is needed to support learners' agency in drawing on all their meaning‐making resources. The presence of recently arrived learners new to English creates contexts for translanguaging, but even fluent bilingual learners benefit from further development of Arabic social studies registers. With ongoing practice, emergent and fluent bilinguals participated in inquiry practices through translanguaging. Support for translanguaging in the context of learning school subjects can enable learners' development of their bilingual meaning‐making potential.
RETRACTED: CAB39 modulates epithelial–mesenchymal transition through NF‐κB signaling activation, enhancing invasion, and metastasis in bladder cancer

AbstractBladder cancer (BC), the predominant urological malignancy in men, exhibits complex molecular underpinnings contributing to its progression. This investigation aims to elucidate the expression dynamics of calcium‐binding protein 39 (CAB39) in both healthy and cancerous tissues and to explore its functional role in the epithelial–mesenchymal transition (EMT) within human bladder cancer contexts. Utilizing immunohistochemistry and quantitative reverse transcription analyses, we assessed CAB39 expression across BC specimens and cell lines. Further, we implemented wound healing, cell invasion, and CCK‐8 proliferation assays in CAB39‐knockdown cell lines, alongside a nude mouse xenograft model, to gauge the impact of diminished CAB39 expression on the invasive, migratory, and proliferative capacities of BC cells. Our gene set enrichment analysis probed into the repertoire of genes augmented by increased CAB39 expression in BC cells, with subsequent validation via western blotting. Our findings reveal a pronounced overexpression of CAB39 in both BC tissues and cellular models, inversely correlated with disease prognosis. Remarkably, the oncogenic trajectory of bladder cancer was mitigated upon the establishment of shRNA‐mediated CAB39 knockdown in vitro and in vivo, effectively reversing the cancer's invasive and metastatic behaviors and curbing tumorigenesis in xenograft models. Hence, CAB39 emerges as a critical biomarker for bladder cancer progression, significantly implicated in facilitating EMT via the upregulation of neural cadherin (N‐cadherin) and the suppression of epithelial cadherin through NF‐κB signaling pathways. CU‐T12‐9 effectively overturned the downregulation of p65‐NF‐kB and N‐cadherin, key elements involved in EMT and cell motility, induced by CAB39 knockdown. This study underscores CAB39's pivotal role in bladder cancer pathophysiology and its potential as a therapeutic target.
Supersymmetric spectrum for vector multiplet on Euclidean AdS2
Authors: Lezcano Alfredo González , Jeon Imtak , Ray Augniva 
Published: August 2024

Abstract
Quantum study of supersymmetric theories on Euclidean two dimensional anti-de Sitter space (EAdS2) requires complexified spectrum. For a chiral multiplet, we showed that the spectrum of the Dirac operator acquires a universal shift of i/2 from the real spectrum to make the supersymmetry between boson and fermion manifest, where both the bosonic and fermionic eigenfunctions are normalizable using an appropriate definition of Euclidean inner product. We extend this analysis to the vector multiplet, where we show that the gaugino requires both +i/2 and i/2 shift from the real spectrum, and there is additional isolated point at vanishing spectral parameter which is mapped by supersymmetry to the boundary zero modes of the vector field. Furthermore, this spectral analysis shows that not every bosonic fields in the vector multiplet can satisfy normalizable boundary condition. Nevertheless, aided by a reorganization of fields into a cohomological form, we find the supersymmetry mapping between bosons and fermions in terms of the expansion coefficients with respect to the newly constructed basis.
Orbifolded elliptic genera of non-compact models
Authors: Ashok Sujay K. , Troost Jan 
Published: August 2024

Abstract
We revisit the flavored elliptic genus of the N=2 superconformal cigar model and generalize the analysis of the path integral result to the case of real central charge. It gives rise to a non-holomorphic modular covariant function generalizing completed mock modular forms. We also compute the genus for angular orbifolds of the cigar and Liouville theory and decompose it in terms of discrete and continuous contributions. The orbifolded elliptic genus at fractional level is a completed mock modular form with a shadow related to U(1) modular invariants at rational radius squared. We take the limit of the orbifolded genera towards a weighted ground state index and carefully interpret the contributions. We stress that the orbifold cigar and Liouville theories have a maximal and a minimal radius, respectively.
Unconventional conformal invariance of maximal depth partially massless fields on dS4 and its relation to complex partially massless SUSY
Authors: Letsios Vasileios A. 
Published: August 2024

Abstract
Deser and Waldron have shown that maximal depth partially massless theories of higher (integer) spin on four-dimensional de Sitter spacetime (dS4) possess infinitesimal symmetries generated by the conformal Killing vectors of dS4. However, it was later shown by Barnich, Bekaert, and Grigoriev that these theories are not invariant under the conformal algebra so(2, 4). To get some insight into these seemingly contradicting results we write down the full set of infinitesimal transformations of the fields generated by the fifteen conformal Killing vectors of dS4. In particular, although the infinitesimal transformations generated by the ten dS Killing vectors are well-known (these correspond to the conventional Lie derivatives), the transformations generated by the five non-Killing conformal Killing vectors were absent from the literature, and we show that they have an ‘unconventional’ form. In the spin-2 case (partially massless graviton), we show that the field equations and the action are invariant under the unconventional conformal transformations. For spin s > 2, the invariance is demonstrated only at the level of the field equations. For all spins s ≥ 2, we reproduce the result that the symmetry algebra does not close on the conformal algebra, so(2, 4). This is due to the appearance of new higher-derivative symmetry transformations in the commutator of two unconventional conformal transformations. Our results concerning the closure of the full symmetry algebra are inconclusive. Then we shift focus to the question of supersymmetry (SUSY) on dS4 and our objective is twofold. First, we uncover a non-interacting supermultiplet that consists of a complex partially massless spin-2 field and a complex spin-3/2 field on dS4. Second, we showcase the appearance of the unconventional conformal symmetries in the commutator of two SUSY transformations. Thus, this commutator closes on an algebra that is neither so(1, 4) nor so(2, 4), while its full structure is an open question. More open questions arising from our findings are also discussed.
Security of quantum position-verification limits Hamiltonian simulation via holography
Authors: Apel Harriet , Cubitt Toby , Hayden Patrick , Kohler Tamara , Pérez-García David 
Published: August 2024

Abstract
We investigate the link between quantum position-verification (QPV) and holography established in [1] using holographic quantum error correcting codes as toy models. By inserting the “temporal” scaling of the AdS metric by hand via the bulk Hamiltonian interaction strength, we recover a toy model with consistent causality structure. This leads to an interesting implication between two topics in quantum information: if position-based verification is secure against attacks with small entanglement then there are new fundamental lower bounds for resources required for one Hamiltonian to simulate another.

Published: August 2024

ZusammenfassungDie Optimierung der medikamentösen Tumortherapie beim Mammakarzinom geht mit einer Deeskalation der operativen Behandlungen einher bei gleichzeitig verbesserten Heilungsergebnissen. Die Daten zu onkologischen Endpunkten und zu den Patient Reported Outcomes (PRO) zeigen schlechtere Ergebnisse für die Mastektomie (ME) im Vergleich zur brusterhaltenden Therapie. Die hautsparende Mastektomie hat vergleichbare onkologische Ergebnisse wie die ME, aber bessere PROs nach der Operation. PROs werden durch die Therapieverfahren beeinflusst und verändern sich über die Zeit. Bei Patientinnen mit einem low-risk Mammakarzinom kann auf die SNB („sentinel node biopsy“) verzichtet werden. Bei cN0 und pN1sn sollte keine ALNE (axilläre Lymphonodektomie) erfolgen, sondern eine Bestrahlung der Axilla. Patientinnen mit cN+ sollten eine neoadjuvante medikamentöse Therapie erhalten und eine SNB/TAD, wenn sie in eine cN0-Situation konvertieren. Bei ypT0 und ypN0sn kann der Verzicht auf eine Bestrahlung der Thoraxwand und LAW diskutiert werden. Die Komplikationsraten sind nach einer epimuskulären geringer als nach einer submuskulären Implantatrekonstruktion. Die komplette Rekonstruktion der Brust durch mehrmaliges Lipofilling ist eine Alternative zur Expander‑/Implantatrekonstruktion. Die intraoperative ICG(Indocyaningrün)-Angiographie, lokale Tranexamsäuregabe und postoperative topische Applikation von Nitroglycerin können die Komplikationsrate der Brustrekonstruktion reduzieren.
A boundary strip indicator for material distribution-based topology optimization
Authors: Setta Mario , Hägg Linus , Wadbro Eddie 
Published: August 2024

AbstractThis article proposes a boundary strip indicator for density-based topology optimization that can be used to estimate the design’s surface area (perimeter in 2D) or identify a coating layer. We investigate the theoretical properties of the proposed boundary strip indicator and propose a differentiable approximation that preserves key properties, such as non-negativity. Finally, we use the boundary strip indicator in a heat conduction design optimization problem for a coated structure. The resulting designs show a strong dependence on the properties of the coating.

with respect to the minimal metric introduced by Forstnerič and Kalaj (Anal PDE 17(3):981–1003, 2024). In particular, we prove that every bounded strongly minimally convex domain is Gromov hyperbolic and its Gromov compactification is equivalent to its Euclidean closure. Moreover, we prove that the boundary of a Gromov hyperbolic convex domain does not contain non-trivial conformal harmonic disks. Finally, we study the relation between the minimal metric and the Hilbert metric in convex domains.

We obtain estimates of the fibered Lyapunov exponents and show that in the limit as b tends to infinity, they approach the values of the Lyapunov exponents for the corresponding random case. The estimates are based on a control of the distribution of the iterates of almost every point, up to a fixed (small) scale, depending on b.
Riparian Landscape Change: A Spatial Approach for Quantifying Change and Development of a River Network Restoration Model
Authors: Stieger Martin , Mckenzie Paul 
Published: August 2024

AbstractNatural river landscapes can be biodiversity hotspots but are one of the most human altered ecosystems with habitats significantly damaged around the world, and a third of fish populations threatened with extinction. While riparian ecosystems have been negatively altered by anthropogenic activities, effective planning and restoration strategies can reverse negative impacts by improving habitat quality. However, restoring rivers requires appropriate data on current riparian health while also considering priorities for different stakeholders. To address this, a Geographic Information System (GIS) was used to create a new and transferable restoration priority model based on a section of the river Linth in Switzerland as a case study. The restoration priority model is founded on connectivity, river condition, national priority species and species hotspots. Landscape change of the riparian zone was analyzed using aerial imagery and landscape metrics. Almost a quarter of rivers within the study area were considered high or very high restoration priority, with many aquatic species set to benefit from restoration. From 1946 to 2019, the riparian landscape became highly fragmented due to significant growth in impervious surfaces and a concomitant loss of agricultural land. The GIS model provides a tool by which environmental agencies can manage natural features over large scales, while also planning priorities and targeting conservation strategies to the areas of greatest need.
Venous thromboembolism risk in adults with hereditary thrombophilia: a systematic review and meta-analysis
Authors: Alnor Anne B. , Gils Charlotte , Vinholt Pernille J. 
Published: August 2024

Abstract
This systematic review and meta-analysis assesses venous thromboembolism (VTE) risk in adults with hereditary thrombophilia, including Factor V Leiden (FVL) mutation, prothrombin G20210A (FII) mutation, compound heterozygosity, protein C (PC), protein S (PS), and antithrombin (AT) deficiency. Eligibility criteria included studies suitable for quantitative synthesis with extractable information on VTE risk in adults (> 15 years). There were no restrictions on VTE type, location, or occurrence. Two authors reviewed all studies and extracted data from 107 publications, encompassing 107,130 individuals (21,560 experiencing VTE). We used a random effects model and calculated odds ratios (ORs) with 95% confidence intervals (CIs). The highest risk was associated with homozygous FVL (OR 5.58, 95% CI 4.61–6.74), homozygous FII (OR 5.16, 95% CI 3.12–8.52), and compound heterozygosity (OR 4.64, 95% CI 2.25–9.58). In contrast, VTE risk was lowest for FVL heterozygosity (OR 2.97, 95% CI 2.41–3.67) and FII heterozygosity (OR 2.21, 95% CI 1.70–2.87), whereas PC (OR 3.23, 95% CI 2.05–5.08), PS (OR 3.01, 95% CI 2.26–4.02), and AT deficiency (OR 4.01, 95% CI 2.50–6.44) demonstrated an intermediate VTE risk. These results highlight an increased risk of venous thromboembolism in adults with hereditary thrombophilia. However, the risk for patients with PC, PS, and AT deficiency appears to be lower than previously stated, likely due to varying thrombogeneity of the underlying genetic mutations. Further research addressing this aspect of VTE risk in hereditary thrombophilia is imperative to improve patient management.

Abstract
Background
A significant proportion of patients with heart failure (HF) progress to an advanced stage, which is associated with a substantial increase in morbidity and mortality. These patients may be eligible for advanced treatment strategies such as mechanical circulatory support with ventricular assist devices (VAD). Vascular dysfunction is a hallmark of heart failure pathophysiology and prognosis. However, whether and to what degree the hemodynamic benefits of VADs influence vascular function remain unknown.

Methods and results
In this study, we evaluated endothelial vascular function with flow-mediated vasodilatation (FMD) and with flicker-light induced retinal vasodilatation (FID). 34 patients with a VAD (age 58 ± 10 years, 85% male, 74% ischemic heart disease, 26 continuous-flow (CF)-LVAD, and 8 pulsatile biventricular (bi)-VAD) were compared to 34 propensity-matched patients (mean age 62 ± 9 years, 68% male, 59% ischemic heart disease) with advanced HF (AdvHF). Endothelial function of larger arteries (FMD) was significantly better in patients after VAD implantation compared to matched AdvHF patients (7.2 ± 4.6% vs. 5.0 ± 3.2%, p = 0.03), whereas microvascular arteriolar function (FIDart) did not differ (0.99 ± 1.43% vs. 1.1 ± 1.7%, p = 0.78). The arterio-venous ratio (AVR) was higher in the VAD group (0.90 ± 0.06 vs 0.85 ± 0.09, p = 0.01), reflecting wider retinal arteriolar and narrower venular diameters. There was no difference in vascular function between patients with CF-LVAD and pulsatile Bi-VAD.

Conclusion
In patients with advanced heart failure, VAD implantation was associated with better endothelial function at the level of large arteries, but not in the microcirculation.
