This study aims to determine the rainfall distribution calculations, the consistency of rainfall data, and the drainage channel dimensions on the Pondoktisuk-Kebonkai road section Sta 1+700 – 1+800 in Nagrak District, Sukabumi Regency. The methodology used includes literature review, field observation, collection of primary data such as daily rainfall data over the past 14 years and catchment area data, as well as secondary data including field documentation and location maps. Hydrological analysis was conducted through maximum rainfall calculation, design rainfall calculation, consistency data testing, probability distribution, distribution fitting tests, rainfall intensity analysis, rainwater storage volume calculation, concentration time calculation, flood discharge analysis, and open drainage dimension calculation. The results show that the calculated water flow velocity is 1.323 m/s with a slope of 0.20%. Based on the checking process, the design meets the standard requirements for allowable water flow velocity (1.50 m/s) and slope (1%). A comparison of the planned drainage slope with the existing land slope at the study site indicates that the calculated slope is lower than the existing slope (1%), thus requiring the design of a flow breaker. The rainfall distribution calculation for the Pondoktisuk-Kebonkai road section Sta 1+700 – 1+800 in Nagrak District, Sukabumi Regency, represents all the methods used, with the Gumbel method showing the highest rainfall in all return periods. The rainfall data consistency calculation indicates that Q/n^0.5 and R/n^0.5 are smaller than their critical values, at 0.32 and 0.51 respectively, thus the data is deemed consistent. The drainage channel dimension of 80x80x100 cm with a thickness of 10 cm meets the requirements, with a calculated water flow velocity of 1.323 m/s and a slope of 0.20%, lower than the allowable limits, necessitating the inclusion of a flow breaker.

Published: January 2025

This study employs Critical Discourse Analysis (CDA) to examine the environmental narratives presented in the chapter “Love Your Environment” from an English Language Teaching (ELT) textbook for Grade 11. Through a detailed linguistic analysis, the research focuses on the eco-lexicons, grammatical structures, and discursive strategies used to convey environmental ideologies. The study reveals that the chapter constructs a discourse of individual responsibility, primarily emphasizing personal actions like waste management and recycling while neglecting systemic factors such as corporate or governmental roles in environmental degradation. The use of evaluative adjectives, modal verbs, and passive constructions further reinforces a neoliberal environmental ideology that frames environmental problems as solvable through personal behavior. The findings suggest that while the textbook promotes environmental awareness, it limits students’ understanding of the broader, interconnected nature of environmental issues, potentially impeding the development of critical ecological literacy. This research contributes to the growing field of ecolinguistics and highlights the need for ELT materials to adopt a more holistic and critical approach to environmental education.

Published: January 2025

Nearly 82% of rural areas still rely on the agricultural sector, one of which is the cultivation of food crops and horticulture. Changing climatic conditions are one of the causes of farmers’ failure to predict the selection of the right time for the cultivation process. This work predicts the selection of the right time for the cultivation of certain crops in order to optimize crop yields. Forecasting uses several machine learning methods by comparing the best results. The results showed that machine learning could produce good information at the right time and on certain types of plants to be cultivated in an area. Predictive recommendations for planting corn in 2022 are optimum planting in January to March 2022 and in August to December 2022. The optimum fertilizer application is N fertilizer dose = 100-270 kg/ha, P fertilizer dose = 63-100 kg/ha, and K fertilizer dose = 156-200 kg/ha.

Published: January 2025

Cervical cancer is at the top of the list of women’s gynecologic cancers in developing countries. Various compounds have been developed to fight cancer, but none of these compounds cause satisfactory effects. Much research has been done on anticancer drug ingredients from nature. The tomcat beetle (Paederus fuscipes) contains pederin, pseudopederin, and pederone toxins, which are suspected to have interactions and ADMET profiles against ERα receptors (3ERT) compared to the anti-cancer drugs genistein and tamoxifen. The research includes preparation, RMSD method validation, molecular docking, PreADMET, and visualization. Data were analyzed by comparing bond energy, type of bond, and ADMET (Absorption, Distribution, Metabolism, Excretion, and Toxicity). The results obtained were the bond energies of tamoxifen -10.68 kcal/mol, genistein -7.87 kcal/mol, pederin -7.57 kcal/mol, pseudopederin -8.07 kcal/mol, and pederone -7.83 kcal/mol. The compound from the tomcat beetle with the lowest bond energy is pseudopederin. Amino acid residue interactions in P. fuscipes compounds have similarities with tamoxifen, and genistein mechanism as SERMs (selective estrogen receptor modulators). In PreADMET study, results showed that genistein, compared to tamoxifen, has more toxic effects than compounds from P. fuscipes. As conclusion, the compounds in P. fuscipes have the potential to be developed as a candidate for anticancer agents through inhibition of the alpha estrogen receptor (3ERT) based on in silico study.

Photopolymers: beyond the standard approach to photosensitisation
Authors: Naydenova Izabela , Martin Suzanne , Toal Vincent
Published: January 2025

A photopolymerizable material for use in the visible normally consists of a dye sensitizer, a free radical generator, monomer/monomers and, optionally, a binder, and is prepared usually as a dry or liquid film. Upon illumination with light of appropriate wavelength, a photopolymerisation reaction is triggered, leading to a change in the film’s refractive index. Because the presence of the dye is essential, the film is usually made sensitive to light during its preparation. Here we separate the film preparation and the sensitisation processes. In this way the photopolymerisation process can be used to detect dye labelled analytes, providing an alternative to fluorescence detection methods that offers visual, easy to interpret information. Our approach also allows for a precise control of the spatial location of the photoinduced refractive index changes that can be utilised for holography, lithography and photonic device fabrication.

Authors: Ikari Tomofumi , Guo Ruixiang , Minamide Hiroaki , Ito Hiromasa
Published: January 2025

We experimentally demonstrated the scalability of the terahertz (THz)-wave parametric oscillator by using a pump beam with a wide aperture and a high pulse energy. THz-wave absorption by the LiNbO3 crystal in the oscillator is substantially suppressed by employing a surface-emitting cavity configuration. We also improved the conversion efficiency by increasing the parametric interaction in the noncollinear phase-matching geometry. A pump depletion of 54% and a conversion efficiency of 0.9 × 10−6 are achieved. A maximum THz output of 382 nJ/pulse was achieved at 1.46 THz using a 8.0 mm-diameter pump beam with a pulse energy of 465 mJ/pulse.

Published: January 2025

In the last two decades, there has been growing interest in silicon-based photonic devices for many optical applications: telecommunications, interconnects and biosensors. In this work, an advance overview of our results in this field is presented. Proposed devices allow overcoming silicon intrinsic drawbacks limiting its application as a photonic substrate. Taking advantages of both non-linear and linear effects, size reduction at nanometric scale and new two-dimensional emerging materials, we have obtained a progressive increase in device performance along the last years. In this work we show that a suitable design of a thin photonic crystal slab realized in silicon nitride can exhibit a very strong field enhancement. This result is very promising for all photonic silicon devices based on nonlinear phenomena. Moreover we report on the fabrication and characterization of silicon photodetectors working at near-infrared wavelengths based on the internal photoemission absorption in a Schottky junction. We show as an increase in device performance can be obtained by coupling light into both micro-resonant cavity and waveguiding structures. In addition, replacing metal with graphene in a Schottky junction, a further improve in PD performance can be achieved. Finally, silicon-based microarray for biomedical applications, are reported. Microarray of porous silicon Bragg reflectors on a crystalline silicon substrate have been realized using a technological process based on standard photolithography and electrochemical anodization of the silicon. Our insights show that silicon is a promising platform for the integration of various optical functionalities on the same chip opening new frontiers in the field of low-cost silicon micro and nanophotonics.
A novel method of measuring upwelling radiance in the hydrographic sub-hull
Authors: Rüssmeier N. , Zielinski O.
Published: January 2025

In this study we present a new method useful in collecting upwelling radiance (Lu) from a platform submerged in a hydrographic sub-hull or moon pool of a research vessel. The information analyzed here was obtained during a field campaign in the Northwestern European shelf seas aboard the new research vessel SONNE. As the platform was located at the center of the ship, there is minimal effect from pitch and roll which is known to influence upwelling radiance observations. A comparison of the measurements from this platform with a free falling hyperspectral profiler was performed to determine the degree of uncertainty that results from ship shadow. For given Lu(λ) in situ data we observed ±33% intensity deviations compared to profiling measurements that can be attributed to instrument shading during moon pool installation and environmental perturbations. Furthermore Lu(l) in situ spectra variations were observed at lower wavelengths, therefore a form fitting algorithm was adapted to receive corresponding depths with identical spectral form from Lu(z, λ) profiler casts. During an east to west transect in North Sea with a schedule speed up to 12 knots in situ radiance reflectance rrs(7, λ) measurements at 7 meter depth were performed with this novel radiometer setup. In spite of any restrictions originating from the sub-hull installation, water masses mixing zone from CDOM dominated coastal waters in the Skagerrak Strait towards the open North Sea were successfully derived thus offering an underway applicable upwelling radiance sensing not suffering from sun glint or other typical restrictions of above water radiometer installations.

Ethics: The Elixir of Publications
Authors: Singhal Manphool , Basu Suprit , Sharma Arun , Singh Paramjeet
Published: January 2025

Scientific papers are the driving force for research, information dissemination, and policymaking that directly impacts society. Thus, ethical practices are the elixir of publications. Adherence to ethical practices promotes integrity in research and publication. Transgression of ethics is thus considered a poison to science. Although there is no definition of ethics, it includes a systematic approach that not only recommends but also defends and protects concepts of the conduct of right and wrong. Therefore, ethical principles should be strictly adhered to and upheld at any cost for the progression of science. This article addresses various actions that are considered ethical misconduct and guidelines to fix them. Recommendations of various organizations related to the ethics in publications are also discussed.

Intraoperative Computed Tomography in Orthopaedic Trauma Surgery
Authors: Keil Holger , Vetter Sven Y. , Grützner Paul Alfred , Franke Jochen
Published: January 2025

Background When using mobile 3D C-arms, impairments in image quality occur due to artefacts caused by metal implants as well as to the limited field of view. To avoid these restrictions, special computed tomography devices were designed, in order to improve image quality and to meet requirements for intraoperative usage.

Objectives To analyse practicability and benefits of a mobile intraoperative CT device (Airo, Brainlab, Munich, Germany) on the basis of several parameters that were obtained during a 40-month period.

Materials and Methods All procedures that were performed with usage of intraoperative CT between January 2017 and April 2020 were analysed with respect to anatomical region, count of scans, duration of scans, consequences drawn from the scans and use of navigation.

Results 354 CT-scans were performed in 171 patients (mean 2.07 [1–6] scans per procedure). 47.81% of the procedures were spinal, 52.19% affected the pelvis. 83% of the procedures were navigated. In 22% of patients, improvement in implant placement or reduction was achieved; in most patients (55%), a guidewire for pedicle screws was corrected. The mean scan duration was 10.33 s (3.54–21.72).

Conclusions Use of intraoperative CT was reliable and helpful. Integration in OR standards requires more effort than mobile 3D C-arms. Image quality was outstanding for intraoperative conditions and allowed proper assessment of implant placement and reduction in all cases. Due to the high financial outlay of the system and the good image quality of 3D C-arms in the extremities, we assume that this procedure can be applied in intraoperative CT in traumatological cases in spinal and pelvic surgery in high-level trauma centres.
Importance of Hip-Spine Syndrome in Hip Arthroplasty: Influence on the Outcome and Therapeutic Consequences
Authors: Langer Severin , Stephan Maximilian , von Eisenhart-Rothe Rüdiger
Published: January 2025

Correct interaction between the spine, pelvis, and hip is an essential condition for successful progress after total hip replacement. Spinal pathologies, such as degeneration, fractures, and spinopelvic imbalance with and without lumbar fusions, are closely associated with an increased risk of impingement or even dislocation of the prosthesis. To significantly reduce this risk, various parameters are required to quantify the risk groups. Knowledge on the presence of stiffness of the spine (change in pelvic tilt between standing and sitting at < 10°) and sagittal spinal deformity (pelvic incidence–lumbar lordosis mismatch > 10° or 20°) is essential in identifying patients with corresponding risk. The individual risk profile can be assessed through a specific history and examination. Before total hip arthroplasty, a routine preoperative workup is recommended for high-risk patients: using information from standardised preoperative radiographs while sitting and standing (pelvis, anteroposterior view, lying and standing; spine and pelvis, lateral view, standing and sitting). Important changes can be made during the surgery. If the spine is stiff, attention should be paid to the position of the cup, with increased anteversion, sufficient offset, and larger head that is secure to dislocation – to reduce the risk of dislocation. In the case of a sagittal spinal deformity, the functional coronary pelvic level must be carefully controlled so that it is better to use double mobility cups. Digital systems, such as navigation and robotics, can optimise component positioning although, so far, there is little evidence that the complication rate decreased. Therefore, further studies are warranted.
Effects of an Integrated Geriatric-Orthopedic Co-management (InGerO) on the Treatment of Older Orthopedic Patients with Native and Periprosthetic Joint Infections
Authors: De Bueck Ulrike , Kohlhof Hendrik , Wirtz Dieter Christian , Lukas Albert
Published: January 2025

Purpose In view of our aging society, co-management with a geriatrician is becoming increasingly important. While such collaborations have been working successfully in trauma surgery for years, it is still unclear whether they are also helpful for non-trauma patients in orthopedics. The aim of this study was to investigate the effect of such a cooperation in orthopedic non-trauma patients with native and periprosthetic joint infections on the basis of five key areas.

Methods A retrospective observational study as a before and after comparison was used to compare routine data from patients with and without orthogeriatric co-management after nontraumatic surgery. Eligible patients for the study were 70 years and older, had a diagnosis of hip, knee, or shoulder infection, and had been hospitalized for at least 14 days. Co-management consisted of close follow-up by a geriatrician, Comprehensive Geriatric Assessment, and “complex early geriatric rehabilitation”. The comparison group received therapy as usual, without a geriatrician and without “complex early geriatric rehabilitation”. Special attention was paid to delirium, pain, mobility, postoperative complications, and renal function.

Results Analysis was carried out with 59 patients “with” and 63 “without” geriatric co-management. In the co-management group, delirium was detected significantly more often (p < 0.001), significantly lower pain intensities were measured at the time of discharge (p < 0.001), transfer ability had clearly improved more (p = 0.04), and renal function was more frequently noted (p = 0.04). No significant differences were found with respect to principal diagnoses, surgical procedures performed, complication rates, pressure ulcer and delirium incidence, operative revisions, or length of inpatient stay.

Conclusion Orthogeriatric co-management in orthopedic patients with native and periprosthetic joint infections and nontraumatic surgery appears to have positive impacts on recognition and treatment of delirium, pain management, transfer performance, and attention to renal function. Further studies should follow in order to conclusively assess the value of such co-management in orthopedic nontraumatic surgery patients.

Authors: Rüwald Julian , Ploeger Milena Maria , Hischebeth Gunnar T , Tüllmann Mareike , Roos Jonas , Gathen Martin , Kabir Koroush
Published: January 2025

Background Percutaneous screw fixation for pelvic fractures has become a minimally invasive alternative to an open operation. The complex anatomy of the pelvis renders this procedure challenging. The objective of this study was to assess standardized angles and dimensions of safety zones within a 3 D computed tomography model for optimal supra-acetabular screw placement.

Methods Computed tomography scans of 107 patients that suffered major trauma without showing any bone injury of the pelvis were collected. Using a software-based analysis, raw computed tomography data were transformed into 3 D models to set standardized landmarks and determine the possible insertion corridor.

Results Screws not exceeding a length of 97 mm in females and 106.4 mm in males were, in 95% of the evaluated cases, insertable without cortical bone penetration. The safety zone was 6.6 mm for females and 7.9 mm for males. Screws not exceeding these diameters were safely insertable in 95% of the cases. For the midsagittal plane, the angle was 36.4 ± 5.1 on the left and 34.7 ± 2.9 on the right (p = 0.008). For the anterior pelvic plane, the angle was 31.3 ± 4.5° on the left and 34.0 ± 4.8° on the right (p = 0.008).

Conclusions Percutaneous fixation using supra-acetabular screws is a promising method to treat simple supra-acetabular fractures. These results may improve its safe utilization and could facilitate its broader clinical application.
Deep Learning in the Detection of Rare Fractures – Development of a “Deep Learning Convolutional Network” Model for Detecting Acetabular Fractures
Authors: Erne Felix , Dehncke Daniel , Herath Steven C. , Springer Fabian , Pfeifer Nico , Eggeling Ralf , Küper Markus Alexander
Published: January 2025

Background Fracture detection by artificial intelligence and especially Deep Convolutional Neural Networks (DCNN) is a topic of growing interest in current orthopaedic and radiological research. As learning a DCNN usually needs a large amount of training data, mostly frequent fractures as well as conventional X-ray are used. Therefore, less common fractures like acetabular fractures (AF) are underrepresented in the literature. The aim of this pilot study was to establish a DCNN for detection of AF using computer tomography (CT) scans.

Methods Patients with an acetabular fracture were identified from the monocentric consecutive pelvic injury registry at the BG Trauma Center XXX from 01/2003–12/2019. All patients with unilateral AF and CT scans available in DICOM-format were included for further processing. All datasets were automatically anonymised and digitally post-processed. Extraction of the relevant region of interests was performed and the technique of data augmentation (DA) was implemented to artificially increase the number of training samples. A DCNN based on Med3D was used for autonomous fracture detection, using global average pooling (GAP) to reduce overfitting.

Results From a total of 2,340 patients with a pelvic fracture, 654 patients suffered from an AF. After screening and post-processing of the datasets, a total of 159 datasets were enrolled for training of the algorithm. A random assignment into training datasets (80%) and test datasets (20%) was performed. The technique of bone area extraction, DA and GAP increased the accuracy of fracture detection from 58.8% (native DCNN) up to an accuracy of 82.8% despite the low number of datasets.

Conclusion The accuracy of fracture detection of our trained DCNN is comparable to published values despite the low number of training datasets. The techniques of bone extraction, DA and GAP are useful for increasing the detection rates of rare fractures by a DCNN. Based on the used DCNN in combination with the described techniques from this pilot study, the possibility of an automatic fracture classification of AF is under investigation in a multicentre study.

Published: January 2025

Dual-mobility cups (DMCs) were introduced in France more than 40 years ago and are increasingly used not only in hip revision but also primary hip arthroplasty. Due to a simulated large-head articulation and increased jumping distance, DMCs can contribute to a high range of motion in the hip joint and reduce the risk of instability. Numerous studies have reported low dislocation rates and high survival rates in the mid-term follow-up. Nevertheless, long-term data, especially on primary hip replacement, remain limited, and the effect of recent designs and material innovations is still unclear. Therefore, primary DMCs are mainly proposed in patients at high risk for dislocation (i.e. pelvitrochanteric insufficiency, compromised spinopelvic mobility, neuromuscular disorders, obesity and femoral neck fractures). Based on a review of recently published studies referring to these indications, the current study discusses the advantages and disadvantages of DMCs.

Authors: Wang Chong , Lan Shuhua , Xie Panpan , Yang Ruifeng
Published: January 2025

Background Venous thromboembolism (VTE) is one of the major and potentially life-threatening complications following major orthopedic surgeries. Research evidence comparing the effectiveness of rivaroxaban and enoxaparin for thromboprophylaxis specific to total hip arthroplasty (THA) has been limited. Hence, this review was done to compare the efficacy and safety of rivaroxaban against enoxaparin for thromboprophylaxis after THA.

Materials and Methods We conducted a search in databases including Medline, EMBASE, ScienceDirect, Google Scholar, and Cochrane Library from inception until May 2021. Randomized controlled trials directly comparing the effectiveness of rivaroxaban and enoxaparin for thromboprophylaxis among patients undergoing THA were eligible for inclusion. Outcome parameters assessed were efficacy in terms of total VTE and all-cause mortality, major VTE, deep vein thrombosis, symptomatic VTE, and safety in terms of major bleeding events, clinically relevant nonmajor bleeding events, minor bleeding events, total bleeding events, drug-related adverse events, and wound infection. We performed a meta-analysis with a random effects model and reported a pooled risk ratio (RR) with a 95% confidence interval (CI).

Results Eleven studies, including 9057 participants, were analyzed. Amongst efficacy outcomes, VTE and all-cause mortality pooled an RR of 0.58 (95% CI: 0.34–0.99), major VTE pooled an RR of 0.37 (95% CI: 0.15–0.90), deep vein thrombosis pooled an RR of 0.57 (95% CI: 0.32–1.02), and symptomatic VTE pooled an RR of 0.51 (95% CI: 0.30–0.87). Amongst safety outcomes, major bleeding events pooled an RR of 1.18 (95% CI: 0.77–1.80), total bleeding events pooled an RR of 1.12 (95% CI: 0.93–1.34), drug-related adverse event pooled an RR of 0.99 (95% CI: 0.87–1.12), and wound infection pooled an RR of 1.11 (95% CI: 0.58–2.14).

Conclusion Rivaroxaban is a more efficacious drug in terms of VTE and all-cause mortality compared to enoxaparin following THA, and rivaroxaban was non-inferior in terms of safety profiles such as wound infection, bleeding, and drug-related adverse events.

Background Raised complication rates have been reported for total hip arthroplasty (THA) in posttraumatic hip joints after acetabular fractures with prior open reduction and internal fixation (ORIF). The present study evaluated (I) postoperative surgical site infection and the risk of early infection following THA in posttraumatic hip joints after acetabular fractures and (II) the discriminatory ability of preoperative C-reactive protein (CRP) blood levels for periprosthetic joint infection (PJI).

Materials and Methods Patients were included who had undergone THA (2014–2019) after prior ORIF, and nonsurgically treated acetabular fractures. Patients’ demographics and the duration between fracture and THA implantation were assessed. Preoperative diagnostic testing (laboratory results, hip aspirations) as well as the results of intraoperative microbiological swabs and sonication were also evaluated. Postoperative complications were recorded.

Results Sixty-seven patients (51 men/16 women) were included, with a mean age of 54.7 ± 14.0 years (range: 18.0–82.9). The mean time between acetabular fracture and THA was 13.5 ± 14.9 years (0.2–53.5). Four subgroups were classified: subgroup I (nonsurgical, n = 15), subgroup II (complete removal of osteosynthesis, n = 8), subgroup III (partial removal of osteosynthesis, n = 15), and subgroup IV (remaining osteosynthesis, n = 29). Preoperative CRP blood levels were normal. CRP levels had no discriminatory ability to predict PJI (AUC: 0.43). Positive microbiological swabs were assessed in subgroups III (n = 1) and IV (n = 2). Complications during follow-up occurred in subgroups I (one aseptic loosening [6.7%]), III (one wound revision [6.7%], two low-grade infections [13.3%]), and IV (three low-grade infections [10.3%]).

Conclusion High infection rates were found in patients with THA after acetabular fracture with remaining implants or partial implant removal. Serum CRP alone seems to be a poor predictor. Therefore, an extensive diagnostic algorithm can help to detect an occult infection, including preoperative hip aspiration (microbiological samples and measurements of synovial CRP, WBC, and alpha-defensin levels). Intraoperative tissue samples and sonication results should be obtained during THA implantation.
Bricolage and Entrepreneurial Branding in Finnish Tourism Business SMEs
Authors: Suomi Kati , Aro Kaisa
Published: January 2025

The literature on entrepreneurial marketing has grown over the past 25 years, but entrepreneurial branding remains under-studied. The purpose of the present study was to conceptualize entrepreneurial branding in the context of tourism small- and medium-sized enterprises (SMEs). Firstly, this study seeks to add to the literature on entrepreneurial branding by developing a new definition of entrepreneurial branding, by looking at literatures on both ‘entrepreneurial’ and ‘branding’ addressing the limitations of existing definitions to offer a more complete conceptualization. Secondly, it explores whether and how tourism business SMEs employ bricolage in their entrepreneurial branding. The study adopts a qualitative approach with abductive reasoning. In total, 20 interviewees representing 16 Finnish tourism SMEs were interviewed. The findings demonstrate resource constraints faced by tourism SMEs in entrepreneurial branding. Unique features of the place, such as history and heritage of place, were significant sources for building a unique brand identity for the SMEs, often at little cost. The study exemplifies how companies use domains of bricolage (Baker and Nelson in Administrative Science Quarterly 50(3):329–366, 2005) to manage resource constraints. The study offers new insights into the contents of entrepreneurial bricolage domains (physical inputs, labor, skills, customers, and the institutional environment) within a specific context, while also suggesting a new bricolage domain in entrepreneurial branding—namely, media bricolage. This domain refers to companies’ innovative and proactive generation of unpaid or low-cost media coverage in different channels for the purposes of brand building.
Survival properties and spread rates in non-autonomous spread models

Published: January 2025

As time progresses, the transmission pattern of a disease may change. To more precisely determine the spread behaviors of the disease, we develop non-autonomous topological and random spread models. In this article, we validate the survival characteristics of these spread models and elucidate their connection with mixing properties using the associated ξ-matrices or spread mean matrices. We also introduce the concept of spread rates for both periodic topological and random spread models and provide rigorous formulas for calculating these rates. Additionally, numerical examples and simulation results are provided as supporting evidence for the theory in both topological and random models.
Spectral property of magnetic quantum walk on hypercube
Authors: Wang Ce
Published: January 2025

In this paper, we introduce and investigate a model of magnetic quantum walk on a general hypercube. We first construct a set of unitary involutions associated with a magnetic potential ν by using quantum Bernoulli noises. And then, with these unitary involutions as the magnetic shift operators, we define the evolution operator W(ν) for the model, where ν is the magnetic potential. We examine the point-spectrum and approximate-spectrum of the evolution operator W(ν) and obtain their representations in terms of the coin operator system of the model. We show that the point-spectrum and approximate-spectrum of W(ν) are completely independent of the magnetic potential ν although W(ν) itself is dependent of the magnetic potential ν. Our work might suggest that a quantum walk perturbed by a magnetic field can have spectral stability with respect to the magnetic potential.

Published: January 2025

Thermal conductivity of liquid water is distinct from that of ordinary liquids due to its complex hydrogen bonding network. In this study, we develop the thermal resistance network model, supplemented by molecular dynamics simulations, to calculate the thermal conductivities of water and heavy water over a temperature range of 275–375 and 300–375 K, respectively. The thermal conductivities of both water and heavy water are computed at various temperatures and pressures, and the results provide agreement with experimental data. Furthermore, it is pointed out that our model offers an interpretation of thermal conductivity based on heat paths among water clusters rather than the traditional vibrational modes.

This study demonstrates the reversible transition from perpendicular to in-plane magnetic anisotropy in Co/Pd multilayers induced by hydrogenation, using a magneto-optic Kerr microscope. By controlling hydrogen pressure and exposure time, the transition is separated into coercivity and squareness ratio changes, reflecting reduced perpendicular anisotropy and spin reorientation. The Dzyaloshinskii–Moriya interaction is observed through asymmetric magnetic domain expansion, with hydrogenation causing domains to fragment. These results suggest hydrogenation as a method for precise control of magnetic anisotropy and domain structures.
