AbstractTo reduce the security authentication time cost, forwarding delay, and enhance message security of Beidou communication short messages, this paper proposes a Beidou communication short message encryption technology based on SM9 (Mobile Code Secure Communication). This technology uses split hierarchical clustering algorithm to cluster the short message data of Beidou Communication, in order to unify the processing of similar short message data and improve the encryption efficiency of subsequent short messages. Based on the data clustering results, this paper constructs a short message forwarding verification model using the SM9 identification password algorithm, and provides the message content of the communication application protocol and the communication receiving information protocol to achieve low‐cost and efficient forwarding verification. In addition, this article improves the initial value selection of Logistic chaotic mapping by coupling the tent map with coupled mapping lattice (CML) in the spatiotemporal chaos model to generate a chaotic initial value sequence, thereby expanding the key space, enhancing the ability to resist exhaustive attacks, enhancing the randomness of the generated key parameters, and optimizing the encryption effect of short messages. The experimental results show that the short message security authentication time of the technology proposed in this article is basically controlled within 25 ms, and the minimum forwarding delay is only 23.9 ms, which can effectively resist attacks and improve the security of Beidou communication.

AbstractAlthough zinc‒air batteries (ZABs) are regarded as one of the most prospective energy storage devices, their practical application has been restricted by poor air electrode performance. Herein, we developed a free‐standing air electrode that is fabricated on the basis of a multifunctional three‐dimensional interconnected graphene network. Specifically, a three‐dimensional interconnected graphene network with fast mass and electron transport ability, prepared by catalyzing growth of graphene foam on nickel foam and then filling reduced graphene oxide into the pores of graphene foam, is used to anchor iron phthalocyanine molecules with atomic Fe‒N4 sites for boosting the oxygen reduction during discharging and nanosized FeNi hydroxides for accelerating the oxygen evolution during charging. As a result, the obtained air electrode exhibited an ultra‐small electrocatalytic overpotential of 0.603 V for oxygen reactions, a high peak power density of 220.2 mW cm‒2, and a small and stable charge‒discharge voltage gap of 0.70 V at 10 mA cm‒2 after 1136 cycles. Furthermore, in situ Raman spectroscopy together with theoretical calculations confirmed that phase transformation of FeNi hydroxides takes place from α‐Ni(OH)x to β‐Ni(OH)x to γ‐Ni(3+δ)+OOH for the oxygen evolution reaction and Ni is the active center while Fe enhances the activity of Ni active sites.

AbstractAlthough MXene has attracted great interest in diverse fields, it is susceptible to oxidation in water (H2O) with transition metal ions such as Co2+, Fe2+, and Cu2+, which is pronounced at high temperatures. This impedes the preparation of MXene‐based composites and their functional applications. Here, this study revealed that Co2+ increases the maximum and average atomic charge of H in H2O to improve the reactivity of H2O, which leads to the fact that Co2+ catalyzes the oxidation of Ti3C2Tx MXene. Furthermore, the addition of N,N‐dimethyl formamide (DMF) reduces the H2O activity and improves the oxidation stability of Ti3C2Tx in the presence of Co2+ via preferentially forming coordination bonds with Co2+. This strategy is also effective in enhancing the oxidation tolerance of Ti3C2Tx to Fe2+ in H2O. Moreover, it is feasible to enhance the oxidation stability of Ti2CTx MXene in H2O with the existence of Co2+. By virtue of these, the CoO/Ti3C2Tx composite was successfully prepared without obvious Ti3C2Tx oxidation, which is desirable to harness the advantages of Ti3C2Tx as the complementary component for lithium‐ion batteries. This work provides a straightforward paradigm to enhance the oxidation resistance of MXene in H2O in the presence of transition metal ions and at high temperatures, which opens a new vista to use MXene for target applications.

AbstractObjectivesRacial disparities persist despite attempts to establish an egalitarian framework for surgical care. This study aimed to investigate racioethnic disparities in comorbidities and outcomes following surgery for head and neck tumors.MethodsThis retrospective study included adult patients who underwent head and neck oncologic surgery between 2008 and 2020 from the National Surgical Quality Improvement Program. Multivariable regression analyses were conducted to explore the association of the following racioethnic categories with postoperative outcomes: White, Black, Hispanic, and Asian.ResultsA total of 113,234 patients were included in the study, comprising 78.3% White, 8.7% Black, 6.9% Hispanic, and 6.0% Asian patients. Black patients had higher rates of pre‐existing comorbidities compared to White patients. Specifically, the rates of comorbidities such as diabetes mellitus (19.8% vs. 12.4%), hypertension (57.5% vs. 41.5%), smoking history (18.8% vs. 15.0%), dyspnea (7.4% vs. 5.7%), and preoperative anemia (43.6% vs. 36.5%) were higher among Black patients. On regression analyses, Black race was not associated with major morbidity following head and neck oncologic surgeries (odds ratio, 1.098, 95% confidence interval, 0.935–1.289) when compared to White patients. However, there were significant associations between the comorbidities associated with the Black race and an increased risk of major morbidity.ConclusionsBlack patients undergoing head and neck oncologic surgery face a significant challenge due to a higher burden of comorbidities. These comorbidities, in turn, have been found to be associated with postoperative major morbidity.
Untacking small RNA profiling and RNA fragment footprinting: Approaches and challenges in library construction
Authors: Shen Zhaokang , Naveed Muhammad , Bao Jianqiang 
Published: May 2024

AbstractSmall RNAs (sRNAs) with sizes ranging from 15 to 50 nucleotides (nt) are critical regulators of gene expression control. Prior studies have shown that sRNAs are involved in a broad range of biological processes, such as organ development, tumorigenesis, and epigenomic regulation; however, emerging evidence unveils a hidden layer of diversity and complexity of endogenously encoded sRNAs profile in eukaryotic organisms, including novel types of sRNAs and the previously unknown post‐transcriptional RNA modifications. This underscores the importance for accurate, unbiased detection of sRNAs in various cellular contexts. A multitude of high‐throughput methods based on next‐generation sequencing (NGS) are developed to decipher the sRNA expression and their modifications. Nonetheless, distinct from mRNA sequencing, the data from sRNA sequencing suffer frequent inconsistencies and high variations emanating from the adapter contaminations and RNA modifications, which overall skew the sRNA libraries. Here, we summarize the sRNA‐sequencing approaches, and discuss the considerations and challenges for the strategies and methods of sRNA library construction. The pros and cons of sRNA sequencing have significant implications for implementing RNA fragment footprinting approaches, including CLIP‐seq and Ribo‐seq. We envision that this review can inspire novel improvements in small RNA sequencing and RNA fragment footprinting in future.This article is categorized under:

Gravitational waves from phase transitions and cosmic strings in neutrino mass models with multiple majorons
Authors: Di Bari Pasquale , King Stephen F. , Rahat Moinul Hossain 
Published: May 2024

Abstract
We explore the origin of Majorana masses within the majoron model and how this can lead to the generation of a distinguishable primordial stochastic background of gravitational waves. We first show how in the simplest majoron model only a contribution from cosmic string can be within the reach of planned experiments. We then consider extensions containing multiple complex scalars, demonstrating how in this case a spectrum comprising contributions from both a strong first order phase transition and cosmic strings can naturally emerge. We show that the interplay between multiple scalar fields can amplify the phase transition signal, potentially leading to double peaks over the wideband sloped spectrum from cosmic strings. We also underscore the possibility of observing such a gravitational wave background to provide insights into the reheating temperature of the universe. We conclude highlighting how the model can be naturally combined with scenarios addressing the origin of matter of the universe, where baryogenesis occurs via leptogenesis and a right-handed neutrino plays the role of dark matter.
Supersymmetric smooth distributions of M2-branes as AdS solitons
Authors: Anabalón A. , Astefanesei D. , Gallerati A. , Oliva J. 
Published: May 2024

Abstract
We show that the singularities of certain distributions of M2-branes can be removed by adding a Wilson loop around a compact direction along the brane. The holographic coordinate naturally ends up before the singularity and the resulting spacetime provides an AdS soliton configuration, albeit possibly supersymmetric. We study the phase space diagram of these M2-branes distributions endowed with Wilson loops and show that different distributions are interconnected, providing a rich structure of phase transitions at zero temperature.

Published: May 2024

AbstractThe concept of Gromov hyperbolicity is a geometric concept that leads to a rich general theory. Johnson and Kneser graphs are interesting combinatorial graphs defined from systems of sets. In this work we compute the precise value of the hyperbolicity constant of every Johnson graph. Also, we obtain good bounds on the hyperbolicity constant of every Kneser graph, and in many cases, we even compute its precise value.
Ambulantes psychosoziales Screening in einem Hautkrebszentrum: Akzeptanz, psychosoziale Belastung und Inanspruchnahme von Beratungsangeboten
Authors: Wünsch Alexander , Jeske Niklas , Röderer Natalie , Meiss Frank 
Published: May 2024

Zusammenfassung
Hintergrund
Die psychosoziale Versorgung von Krebspatienten nimmt über den gesamten Verlauf der onkologischen Behandlung einen wichtigen Stellenwert ein. Seit 2015 ist das psychosoziale Screening in den Ambulanzen des Hauttumorzentrums in Freiburg implementiert. Wir präsentieren hier eine Post-hoc-Analyse im Rahmen der Qualitätssicherung.

Fragestellung
Akzeptanz, psychosoziale Belastung und Inanspruchnahme wurden evaluiert. Explorativ untersuchten wir, welche Patienten- und Krankheitsmerkmale mit einer erhöhten subjektiven Belastung zusammenhängen.

Material und Methoden
In einer Vollerhebung von 06/2015 bis 12/2015 wurden die Akzeptanz, die psychosoziale Belastung mittels Distress-Thermometer (DT) und der Beratungswunsch ausgewertet.

Ergebnisse
Von 753 Patienten haben 345 (45,8 %) am psychosozialen Screening teilgenommen und Daten von 310 (m:w 174:136; 89,7 % Melanompatienten, mittlere Zeit seit Erstdiagnose 4,7 ± 3,9 Jahre) konnten ausgewertet werden. Die mittlere Belastung auf dem DT betrug 2,97 ± 2,83 (Median 2, Range 0 bis 10). Eine überschwellige Belastung (DT ≥ 5) wurde von 84 Patienten (28,8 %) angegeben; 34 Patienten (11 %) gaben einen Beratungswunsch an, und 23 Patienten nahmen das Beratungsangebot in Anspruch. Patienten mit überschwelliger Belastung waren jünger, befanden sich häufiger unter laufender oder kürzlich abgeschlossener medikamentöser Therapie und hatten häufiger einen Beratungswunsch.

Diskussion
Neben der Erhebung der Belastung mit validierten Screeninginstrumenten stellt die Erhebung des subjektiven Betreuungswunsches einen wichtigen Parameter zur Identifikation von betreuungsbedürftigen Patienten dar. Junge Patienten und Patienten unter Systemtherapie sollten in den Fokus der Aufmerksamkeit rücken.

Published: May 2024

Abstract
Purpose
To evaluate the performance of MRI for detection of bladder cancer following transurethral resection of bladder tumour (TURBT).

Methods
This single-centre retrospective study included forty-one consecutive patients with bladder cancer who underwent bladder MRI after TURBT. Two uroradiologists retrospectively assessed the presence of tumour using bladder MRI with and without DWI (diffusion weighted imaging) using a five-point Likert scale. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were calculated and inter-reader agreement was assessed. Histopathology was used as the reference standard.

Results
24 out of 41 patients (58.5%) had no residual tumour or Tis (carcinoma in situ) after TURBT. Sensitivity, specificity, PPV and NPV for detection of tumour using T1WI (T1-weighted imaging) and T2WI (T2-weighted imaging) was 50.0%, 54.6%, 21.1%, and 81.8%, respectively and for T1WI, T2WI and DWI combined was 100%, 76.5%, 50.0% and 100%, respectively. Overestimation of tumour was more common than underestimation. MRI showed high accuracy for patients in whom there was no residual tumour (78.9%). Inter-reader agreement for tumour detection improved from fair (κ = 0.54) to moderate (κ = 0.70) when DWI was included.

Conclusion
Non-contrast MRI with DWI showed high sensitivity and relatively high specificity for detection of residual tumour after TURBT. Inter-reader agreement improved from fair to moderate with the addition of DWI. MRI can be useful after TURBT in order to guide further management.

Design of smart magnetic thin-sheet structure based wireless sensors-array arrangement for intraoral-pressure sensing approach

Published: May 2024

AbstractDuring orthodontic treatments, orthodontists want to simultaneously measure different kinds of intraoral pressure of a patient to determine a suitable orthodontic treatment plan for the patient. To achieve this, an intraoral pressure sensors-array with a specific arrangement in the oral cavity is needed. Hence, in this paper, we design a smart magnetic thin-sheet structure based wireless sensors-array arrangement for intraoral-pressure sensing for orthodontics to determine the above suitable treatment plan. In general, the sensors-array consists of multiple sensing modules. Each module consists of two parts: the first part is a transmitting/receiving electromagnet which is connected to a reference electromagnet in a balanced inductance bridge configuration while the second part is a smart magnetic thin-sheet structure based high-permeable sensing diaphragm. A voltage input is applied to the reference electromagnet and transmitting/receiving electromagnet, while the voltage output is measured from the transmitting/receiving electromagnet, respectively (the transmitting/receiving electromagnet can transmit the magnetic flux as well as receive or sense the change of magnetic flux). When the sensing diaphragm (which is placed in proximity to the transmitting/receiving electromagnet) undergoes a displacement, the gap between the sensing diaphragm and transmitting/receiving electromagnet changes. This subsequently changes surrounding magnetic flux, and consequently results in a change in magnetic reluctance between the sensing diaphragm and transmitting/receiving electromagnet. Thus, the voltage output of the transmitting/receiving electromagnet is changed accordingly. Based on this operation principle, furthermore, we use multiple transmitting/receiving electromagnets to form a compact (specifically arranged) sensors-array. The results show that specifically arranged sensors-array can provide measurement results in multiple points in the oral cavity to the orthodontists, as a simplified decision-making reference for the orthodontists to determine the clinical treatment plan for patients.
Meta-analysis: loop ileostomy versus colostomy to prevent complications of anterior resection for rectal cancer
Authors: Yang Shilai , Tang Gang , Zhang Yudi , Wei Zhengqiang , Du Donglin 
Published: May 2024

Abstract
Purpose
Anastomotic leakage is a serious complication of colorectal cancer surgery, prolonging hospital stays and impacting patient prognosis. Preventive colostomy is required in patients at risk of anastomotic fistulas. However, it remains unclear whether the commonly used loop colostomy(LC) or loop ileostomy(LI) can reduce the complications of colorectal surgery. This study aims to compare perioperative morbidities associated with LC and LI following anterior rectal cancer resection, including LC and LI reversal.

Methods
In this meta-analysis, the Embase, Web of Science, Scopus, PubMed, and Cochrane Library databases were searched for prospective cohort studies, retrospective cohort studies, and randomized controlled trials (RCTs) on perioperative morbidity during stoma development and reversal up to July 2023, The meta-analysis included 10 trials with 2036 individuals (2 RCTs and 8 cohorts).

Results
No significant differences in morbidity, mortality, or stoma-related issues were found between the LI and LC groups after anterior resection surgery. However, patients in the LC group exhibited higher rates of stoma prolapse (RR: 0.39; 95%CI: 0.19–0.82; P = 0.01), retraction (RR: 0.45; 95%CI: 0.29–0.71; P < 0.01), surgical site infection (RR: 0.52; 95%CI: 0.27–1.00; P = 0.05) and incisional hernias (RR: 0.53; 95%CI: 0.32–0.89; P = 0.02) after stoma closure compared to those in the LI group. Conversely, the LI group showed higher rates of dehydration or electrolyte imbalances(RR: 2.98; 95%CI: 1.51–5.89; P < 0.01), high-output(RR: 6.17; 95%CI: 1.24–30.64; P = 0.03), and renal insufficiency post-surgery(RR: 2.51; 95%CI: 1.01–6.27; P = 0.05).

Conclusion
Our study strongly recommends a preventive LI for anterior resection due to rectal cancer. However, ileostomy is more likely to result in dehydration, renal insufficiency, and intestinal obstruction. More multicenter RCTs are needed to corroborate this.
Impact of tumor size on overall survival and cancer-specific survival of early-onset colon and rectal cancer: a retrospective cohort study
Authors: Yin Wanbin , Zhang Maorun , Ji Zhe , Li Xiaoping , Zhang Shiyao , Liu Gang 
Published: May 2024

Abstract
Purpose
This study aimed to investigate the impact of tumor size on survival in early-onset colon and rectal cancer.

Methods
Early-onset colon and rectal cancer patients were identified from the Surveillance, Epidemiology, and End Results (SEER) database between 2004 and 2015. Tumor size was analyzed as both continuous and categorical variables. Several statistical techniques, including restricted cubic spline (RCS), Cox proportional hazard model, subgroup analysis, propensity score matching (PSM), and Kaplan–Meier survival analysis, were employed to demonstrate the association between tumor size and overall survival (OS) and cancer-specific survival (CSS) of early-onset colon and rectal cancer.

Results
Seventeen thousand five hundred fifty-one (76.7%) early-onset colon and 5323 (23.3%) rectal cancer patients were included. RCS analysis confirmed a linear association between tumor size and survival. Patients with a tumor size > 5 cm had worse OS and CSS, compared to those with a tumor size ≤ 5 cm for both early-onset colon and rectal cancer. Notably, subgroup analysis showed that a smaller tumor size (≤ 50 mm) was associated with worse survival in stage II early-onset colon cancer, although not statistically significant. After PSM, Kaplan–Meier survival curves showed that the survival of patients with tumor size ≤ 50 mm was better than that of patients with tumor size > 50 mm.

Conclusion
Patients with tumors larger than 5 cm were associated with worse survival in early-onset colon and rectal cancer. However, smaller tumor size may indicate a more biologically aggressive phenotype, correlating with poorer survival in stage II early-onset colon cancer.

Abstract
Background
There is scarce information about the influence of prior myocardial infarction (pMI) on outcomes in patients (pts) with ischaemic HFrEF. We analysed data from the EVIdence based TreAtment in Heart Failure (EVITA-HF) registry.

Methods
EVITA-HF comprises web-based case report data on demography, diagnostic measures, adverse events and 1-year follow-up of patients hospitalized for chronic heart failure ≥ 3 months (CHF) and an ejection fraction ≤ 40%. In the present study, we focused on the outcomes of pts with and without pMI in ischaemic HFrEF.

Results
Between February 2009 and November 2015, a total of 2075 consecutive pts with ischaemic HFrEF were included from 16 centres in Germany. A total of 81.2% were male, and the mean age was 71 years. A total of 61.5% of the pts with ischaemic HFrEF had a history of pMI. These pts were treated less often with PCI (20.0 vs. 31.0%, p < 0.001) or CABG (3.8 vs. 7.7%, p < 0.001). They more often received an ICD (40.9 vs. 28.7%, p < 0.001), but less often a CRT-D (11.3 vs. 19.4%, p < 0.001). After multivariate adjustment, pts with pMI had a greater all-cause mortality after 1 year than those without pMI (hazard ratio 1.4; 95% CI, 1.10–1.79, p = 0.007). The combined endpoint of death, resuscitation or ICD shock after 1 year was greater in patients with pMI (20.8 vs. 16.4%, p = 0.03). Mobility was more often reduced in pts with pMI (46.8% vs. 40.1%, p = 0.03), and overall health status was more frequently worse in patients with pMI than in those 12 months ago (23.1 vs. 15.9%, p = 0.01). More than a quarter of the pts with ischaemic HFrEF were anxious or depressive.

Conclusion
pMI in patients with CHF and ischaemic HFrEF was associated with increased mortality, increased event rates, and worsened health status. Hence, the subgroup of pts with ischaemic HFrEF and pMI is at higher risk and deserves special attention.
