Tight junctions regulate epithelial barrier function and have been shown to be influenced by multiple classes of proteins. Apical integrins have been identified as potential regulators of epithelial barrier function; however, only indirect approaches have been used to measure integrin regulation of the epithelial barrier. Here, we used polymeric nanowires conjugated with anti-integrin β1 antibodies to specifically target apically localized integrins in either their closed or open conformation. Barrier regulation by apical integrins was found to be conformation specific. Nanowires targeting integrins in the closed conformation increased epithelial permeability and caused zonula occludens-1 (ZO-1, also known as TJP1) to change from a linear to a ruffled morphology. Claudin-2 and claudin-4 colocalized with ZO-1 and were also ruffled; however, claudin-1 and claudin-7 remained linear. Ruffling was dependent on myosin light chain kinases (MLCKs) and Rho kinases (ROCKs). Conversely, targeting integrins in the open conformation decreased epithelial permeability and made junctions more linearized. Anti-integrin β1 nanowires differentially affected actin and talin (analyzed using pan-talin antibodies), depending on whether they contained activating or inhibitory antibodies. Thus, apical integrins can act as a conformation-sensitive switch that regulates epithelial barrier function.
Walking kinematics of ants carrying food in the mandibles versus gaster
Authors: Bouisset Guillaume , Merienne Hugo , Fourcassié Vincent
Published: November 2024

The locomotor behavior of an animal strongly depends on the distribution of its body mass. Whenever changes occur in this distribution, the displacement of the body center of mass (CoM) may lead to a loss of balance. Ants are an interesting biological model with which to investigate how an animal copes with such changes because, when they transport food, their CoM may be displaced from its usual position. We studied the ant Formica rufa, whose diet consists mainly of liquid food, stored in the abdomen, but also includes prey transported in the mandibles. We investigated the kinematics of locomotion of the same individuals while walking unloaded and while transporting food internally or externally. We found that the kinematics of locomotion slightly differed in the two types of transport. Ants transporting food in their mandibles adopted a more erect posture and tended to be more often in static instability than ants transporting food internally. In addition, the amplitude of the vertical oscillations of their CoM was higher, which led to a jerky locomotion. However, owing to their erect position, the position of their overall CoM was actually not different from that of unloaded ants. Finally, the mechanical work achieved by ants to rise and accelerate their CoM was smaller in ants transporting food internally than in ants transporting food externally or in unloaded ants. This suggests that the morphology of F. rufa could make the transport of food in the gaster more mechanically efficient than the transport of food in the mandibles.
Effects of hypoxia on the olfactory sensitivity of gilt-head seabream (Sparus aurata)
Authors: Tigert Liam R. , Hubbard Peter C. , Porteus Cosima S.
Published: November 2024

Coastal environments around the world are becoming increasingly hypoxic owing to anthropogenic effects. We hypothesized that, because the olfactory epithelium is in contact with the external environment, decreased external oxygen will impair olfaction. We performed electro-olfactograms on juvenile gilt-head seabream (Sparus aurata) and measured the response to three amino acids at five different concentrations (1×10−7 to 1×10−3 mol l−1) in normoxic (20 kPa O2) and two hypoxic conditions (12.5 and 5.7 kPa O2). For the first time, we show that both mild and moderate hypoxia decreased the olfactory response to two out of three odorants. As more coastal areas become hypoxic, it is important to understand how hypoxia may impair the sensory systems of fishes, which can have individual- and population-level effects and important implications for our food supply.

Published: November 2024

Background

Surgical removal of metastasized paraaortic lymph nodes (PALNs) can prolong the survival of certain patients with colorectal cancer (CRC). However, the role of postoperative chemotherapy in such patients remains unknown.

Patients and Methods

This multicenter retrospective study examined 97 patients with PALN metastasis from CRC who underwent surgical resection at 36 centers in Japan between 2010 and 2015. On the basis of adjuvant chemotherapy (AC) after the lymphadenectomy, patients were classified into non-AC and AC groups (27 and 70 patients, respectively). After the exclusion of patients receiving irinotecan, the latter group was further categorized into 5-fluorouracil (5-FU) and oxaliplatin (L-OHP) subgroups (14 and 52 patients, respectively) according to the use of L-OHP. Background characteristics and postoperative survival were compared among the groups.

Results

Marked differences were not seen in background characteristics, except for neoadjuvant treatment, between the non-AC and AC groups. The AC group exhibited better recurrence-free survival (RFS; p = 0.009) and overall survival (OS; p = 0.040 by the Wilcoxon test) than the non-AC group. However, RFS and OS of the 5-FU group did not differ from those of the L-OHP group (p = 0.73 and p = 0.92 by the Wilcoxon test, respectively).

Conclusions

AC may be associated with improved prognosis of patients after the removal of PALN metastasis from CRC, but L-OHP did not offer additional survival benefits. Prospective studies comparing non-AC with 5-FU- and L-OHP-based AC are needed to confirm these findings.

Published: November 2024

Background

Reactive and external visual-cognitive demands are prevalent in sport and likely contribute to ACL injury scenarios. However, these demands are absent in common return-to-sport assessments. This disconnect leaves a blind spot for determining when an athlete can return to sport with mitigated re-injury risk. Purpose

To characterize relationships between patient-reported outcome measures (PROMs) and cognitive-task interference (i.e., cognitive demands exacerbating neuromuscular impairments) for biomechanical predictors of second ACL injuries during jump landings that involved rapid unanticipated decision making. Methods

Thirty-six persons following primary ACLR (26F/10M, 19.8±1.8 years; 1.71±0.1 m; 69.6±12.8 kg, 1.5±0.6 years post ACLR; Tegner: 6.8±1.8) participated. PROMs of ACL-RSI, and the Forgotten Joint Score-12 Knee (FJS-12) were selected to assess altered psychological state (e.g., confidence, attention toward knee). Jumping tasks under anticipated and unanticipated secondary jump directions were performed. Biomechanical variables were dual-task changes (unanticipated – anticipated) in 1) uninvolved limb hip rotator impulse (DTC_Uni-HRot_Imp), 2) asymmetry of knee extensor moment at initial contact (DTC_KEM_Asym), and 3) range of involved knee abduction angle (DTC_KAbA_Range). Regression models tested for relationships between PROMs and the dual-task change in biomechanical variables. Results: ACL-RSI (DTC_Uni-HRot_Imp (p < 0.001)) and FJS-12 (DTC_KAbA_Range (p = 0.001)) had significant relationships with dual-task change in the opposite direction as expected (worse PROM ➔ less dual-task change). A follow-up analysis indicated that dual-task change was inversely correlated with the baseline estimates for kinetic biomechanical variables (less risky single-task biomechanics ➔ greater dual-task change for Uni-HRot_Imp and KEM_Asym).

Conclusions: The collective results are consistent with higher functioning participants (better PROMs) who also demonstrate desirable biomechanics during single-task conditions being prone to demonstrating the greatest risk-associated DTC in unanticipated scenarios.
Achilles Tendon Mechanical But Not Morphological Properties Change with Rehabilitation in Patients with Chronic Midportion Achilles Tendinopathy

Published: November 2024

Purpose

Achilles tendinopathy (AT) is associated with altered tendon’s morphological and mechanical properties, yet it is unclear whether these properties are reversed upon mechanical loading to promote tendon healing. This study aims to determine the extent to which pathological tendon’s morphological and mechanical properties adapt throughout a 12-week eccentric rehabilitation protocol.

Methods

Forty participants with midportion AT were recruited and participated in a 12-week eccentric rehabilitation program. Function and symptoms were recorded through the Victorian Institute of Sports Assessment-Achilles (VISA-A) and hopping. The tendon’s morphological (i.e. volume, midportion cross-sectional area (CSA) and anteroposterior (AP) diameter) and mechanical (i.e. stiffness, Young’s modulus, and tendon non-uniform displacement) properties were measured at baseline and at 6 and 12 weeks of the intervention.

Results

Significant functional improvements were observed, with VISA-A scores and hopping results showing marked improvements (p < 0.001). Morphologically, no significant changes in volume, midportion CSA, or AP diameter were found, although a trend toward decreased CSA between 30-70% of tendon length was noted. Mechanically, significant increases in Achilles tendon stiffness (p = 0.001) and Young’s modulus (p < 0.001) were observed over the course of the rehabilitation program. No differences in tendon non-uniform displacement were found following a 12-week rehabilitation program.

Conclusions

These findings suggest that tendon adaptation in response to mechanical loading primarily involves changes in mechanical properties rather than morphology, highlighting the complexity and variability in tendon adaptation. Clinically, these mechanical properties could be considered in the load progression throughout rehabilitation as potentially higher strains will be induced when clinical improvements precede mechanical adaptations.

Background Large research consortia can generate tremendous amounts of biological information, including high-resolution soil, vegetation, and climate data. While this knowledge stock holds invaluable potential for answering evolutionary and ecological questions, making these data exploitable for modelling remains a daunting task due to the many processing steps required for synthesis. This might result in many researchers to fall back to a handful of ready-to-use data sets, potentially at the expense of statistical power and scientific rigour. In a push for a more stringent approach, we introduce BEpipeR, an R pipeline that allows for the streamlined synthesis of plot-based Biodiversity Exploratories data. Methods BEpipeR was designed with flexibility and ease of use in mind. For instance, users simply choose between aggregating forest or grassland data, or a combination thereof, effectively allowing them to process any experimental plot data of this research consortium. Additionally, instead of coding, they parse most processing information in a user-friendly way through parameter sheets. Processing includes, among others, the creation of a spatially explicit plot-ID template, data wrangling, quality control, plot-wise aggregations, the calculation of derived metrics, data joining to a large composite data set, and metadata compilation. Results With BEpipeR, we provide a feature-rich pipeline that allows users to process Biodiversity Exploratories data in a flexible and reproducible way. This pipeline might serve as a starting point for aggregating the numerous data sets of this and potentially similar research consortia. In this way, it might be a primer for the construction of consortia-wide composite data sets that take full advantage of the consortia’s rich information stocks, ultimately boosting the visibility and participation of individual research projects. Conclusions The BEpipeR permits the user-friendly processing and plot-wise aggregation of Biodiversity Exploratories data. With modifications, this framework may be easily adopted by other research consortia.
Single-incision laparoscopic cholecystectomy versus conventional multi-port laparoscopic cholecystectomy: A systematic review, meta-analysis, and meta-regression of randomized controlled trials
Authors: Rudiman Reno , Hanafi Ricarhdo Valentino , Wijaya Alma
Published: November 2024

Background Conventional multi-port laparoscopic cholecystectomy (CMLC) has become the current ‘gold standard’ technique in gallbladder disease. Single-incision laparoscopic cholecystectomy (SILC) has gained attention due to its benefits in improving patient cosmetic results and pain reduction. We aim to assess the latest evidence on the feasibility, safety and surgical outcomes of SILC and CMLC. Methods We conducted searches for randomized controlled trials (RCTs) in PubMed, PubMed Central (PMC), and Europe PMC between December 2011 and 2021. The latest search was conducted in January 2022. We analyzed several outcomes, including perioperative complications, estimated blood loss, operation time, conversion to open surgery, hospital stay, pain score, cosmesis, and days of return to work. Cochrane Risk of Bias (RoB) 2.0 tool was used to evaluate quality of studies. Mantel-Haenszel’s formula and Inverse Variance method were conducted to synthesize results. This study was accomplished in accordance with the PRISMA guidelines. Results A total of 37 studies were eligible, with a total of 2,129 and 2,392 patients who underwent SILC and CMLC. Our study demonstrated a superiority of SILC for the visual analog score (VAS) at six hours post-operation [mean difference (MD) -0.58 (95% CI -1.11, -0.05), p=0.03], cosmesis one-month post-operation [standard MD 2.12 (95% CI 1.10, 3.13), p<0.0001], and cosmesis six months post-operation [standard MD 0.53 (95% CI 0.06, 0.99), p<0.0001]. Meanwhile, SILC showed a longer operation time [MD 10.45 (95% CI 6.74, 14.17), p<0.00001]. In terms of VAS at four time points (4, 8, 12, and 24 hours), perioperative complications, estimated blood loss, conversion to open surgery, hospital stay and days to return to work, SILC did not differ from CMLC. Conclusions SILC is a safe, feasible and favorable procedure in terms of pain reduction and cosmetic results. The option between both procedures is based on surgeon preferences.

Correlation of prolonged sitting time and sitting posture on low back pain: A cross-sectional study among medical students at Universitas Sumatera Utara
Authors: Koswara Jocelyn , Machrina Yetty , Lubis Mahrani , Amelia Rina
Published: November 2024

Background Low Back Pain (LBP) is the most common musculoskeletal disorder in the world. Medical students, particularly those who use computers for study purposes, are more vulnerable to LBP due to prolonged sitting times and improper sitting posture during lectures. However, prior research showed that the prevalence of LBP among medical students appeared lower when they were enrolled during online pandemic learning. Hence, this research is performed to determine the correlation between the duration of sitting and sitting posture on the incidence of LBP among medical students in Universitas Sumatera Utara, Indonesia. Methods A cross-sectional study with an analytical descriptive design was conducted in September 2023 among randomly selected 147 medical students at Universitas Sumatera Utara, Indonesia. The inclusion criteria of the research sample are students with BMI< 23 kg/m2 while the exclusion criteria are students who have abnormalities and a history of trauma or spinal fractures. Data was obtained from filling out questionnaires of The Pain and Distress Scale (PAD) and Body Awareness of Postural Habit in Young People (BAPHY). A Chi-square test and logistic regression were used to analyze data with a p-value < 0.05 was regarded as statistically significant. Results The study’s findings revealed that 40.1% of students reported having LBP problems, 72.1% reported sitting for more than seven hours each day, and 33.3% reported having a bad sitting posture. Chi-square analysis revealed a significant correlation between sitting duration and posture on complaints of lower back pain (RR = 1.69, p = 0.041 and RR = 1.69, p = 0.009). At a risk of 2,438 times, sitting posture is the main factor contributing to LBP among medical students at Universitas Sumatera Utara, Indonesia. Conclusions This research showed a significant correlation between duration and sitting posture on the incidence of low back pain.

Background The Indian government is committed to addressing various manifestations of malnutrition, including overweight and obesity, inorder to improve individual health and well-being. The scoping review aims to map existing national policy instruments (programmes, schemes, regulations and guidelines) addressing overweight and obesity in India and analysing them for Social and Behaviour Change Communication (SBCC) strategies. Methods Systematic identification and selection of policy instruments using ‘Arksey and O’Malley’ framework was conducted from central government ministry websites, between March and June 2023. These instruments focused on nutrition and/or physical activity, targeting specific demographic groups like pregnant women, lactating mothers, children (0-5 years and 5-9 years), or adolescents (10-19 years); excluding those focusing on specific diseases like micronutrient deficiencies, wasting, and stunting. Based on search strategy six policy instruments were included and analysed for SBCC strategies. Results While many policy instruments incorporated SBCC plans; the ‘National Programme for Prevention of Non-Communicable Diseases (NP-NCD)’ stands out as a significant policy initiative specifically targeting the prevention of overweight and obesity within the broader context of Non-Communicable Diseases. It adopts a comprehensive approach addressing key drivers contributing to overweight/obesity across multiple levels of behavioural influence i.e., individual, interpersonal, community and organisation for health promotion. However, there’s need to strengthen SBCC strategies related to prevention and management of obesity, especially screening and counselling, to cover all age groups with a particular focus on adolescents and youth. SBCC strategies can also be incorporated into India’s Integrated Nutrition Support Programme (POSHAN 2.0) and/or Reproductive, Maternal, New-born, Child, Adolescent Health and Nutrition (RMNCAH+N) under the National Health Mission. Conclusion This paper underscores the necessity for comprehensive strategies to address multifaceted origins of overweight and obesity. The NP-NCD stands out as a noteworthy initiative, and there is considerable potential for other programmes to emulate SBCC strategies to bolster their overall effectiveness. Note : *Policy instruments throughout the paper have been used to cover programmes, schemes, regulations and guidelines.

Published: November 2024

As post-hoc analyses show, interactive marketing in the new media age has served as a fragmented technique for transitioning from traditional modes of operation to dynamic and customized environments that blur the lines between brands and consumers. Several research papers have been published on interactive marketing, the impact of social media engagement, and brand loyalty. However, they remain fragmented because most produce different results based on different samples at various stages of business development. Nonetheless, there are no systematic reviews that combine all these findings into a comprehensive framework. However, many interactive marketing studies focus on short-term outcomes and do not take into account long-term effects such as brand equity and customer lifetime value. Selected articles were understudied with the requirement of a rigorous review process, which includes a thorough examination of the relevant literature. The implementation of this process is expected to result in the absence of a room for subjective judgment, as all selected studies were carefully evaluated using predetermined criteria. It was determined that the use of these technologies allows brands to interact with their customers in novel and creative ways, resulting in more engaging and dynamic experiences. That is, evaluating the effectiveness of marketing initiatives is critical to understanding their impact.

Published: November 2024

In this paper, we apply the concept of bipolar fuzzy sets to pseudo-UP ideals in pseudo-UP algebras. We prove that the intersection of two bipolar fuzzy pseudo-UP ideals is also a bipolar fuzzy pseudo-UP ideal, while the union of two such ideals does not always result in a bipolar fuzzy pseudo-UP ideal. Additionally, we discuss the concepts of bipolar fuzzy pseudo-UP ideals under homomorphism and explore several related properties. The homomorphic image and inverse image of bipolar fuzzy pseudo-UP ideals in a pseudo-UP algebra are also examined in detail. Furthermore, we study the notion of a bipolar fuzzy pseudo-UP ideal under the Cartesian product of pseudo-UP algebra. The Cartesian product of any two bipolar fuzzy pseudo-UP ideals is also the bipolar fuzzy pseudo-UP ideal of pseudo-UP algebra, and then some related results are obtained. MSC: 03G25, 06D30.

Published: November 2024

Background Temporomandibular disorders (TMD) are diseases of the stomatognathic system characterized by various signs and symptoms. TMD treatment must be multidisciplinary because its causes are multifactorial. Noninvasive conservative treatment strategies should be carried out before considering invasive treatment options that may lead to irreparable damage. Physical therapy is an effective noninvasive therapy for managing the signs and symptoms of TMD. To date, the most effective therapeutic approach for managing TMD pain remains controversial. Therefore, this study aimed to evaluate the most effective physical therapy for pain management, symptom control, and quality of life improvement in patients with TMD. Methods Data search was performed using the PubMed, SCOPUS, and Web of Sciences databases. The results are reported based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement for systematic reviews. Interventions based on physical therapy, including physical exercise, manual therapy, myofacial muscle manipulation, and postural therapy, with pain relief, increased mouth opening, or improved quality of life as primary outcomes, were examined. Results Twenty eligible articles were analyzed. Most interventions demonstrated statistically significant improvements as measured by the study outcomes. Conclusions Most types of physical therapy demonstrated positive effects on patients with TMD. Furthermore, physical therapy for both cervical and regional TMJ manipulation can be an alternative long-term treatment for TMD.

Published: November 2024

Digital therapeutics (DTx) are emerging as a transformative innovation in healthcare offering evidence-based digital interventions for the treatment, management, and prevention of various diseases and disorders. In Korea, DTx have gained significant attention as potential solutions to the increasing burden of chronic diseases and mental health conditions. However, the Korean DTx market faces several challenges that hinder its widespread adoption and integration into the national healthcare system. This study provides a comprehensive analysis of the current state of the DTx market in Korea, identifies the key challenges impeding its growth, and proposes strategies for overcoming these obstacles. This study utilized a literature review and market analysis approach to examine the latest research, industry reports, and regulatory documents related to DTx. The analysis focused on three primary areas: (1) the current regulatory landscape, (2) technological advancements and challenges, and (3) economic and commercial factors influencing DTx adoption in Korea. A comparative analysis of global regulatory practices was also conducted to identify best practices. The findings revealed that while Korea has made significant strides in supporting DTx development, the market remains in its early stages. The key challenges include underdeveloped regulatory frameworks, issues with data quality and security, and a lack of established reimbursement pathways. We recommend developing tailored regulatory frameworks for DTx, enhancing policy support for small and medium-sized enterprises involved in DTx development, and increasing investments in technological infrastructure. By addressing these challenges, Korea could position itself as a leader in the global DTx market, delivering innovative and effective treatments to enhance patient care and outcomes.

Personalized Pricing and Assortment Optimization Under Consumer Choice Models with Local Network Effects
Authors: Xie Tong , Wang Zizhuo
Published: November 2024

We introduce a consumer choice model where each consumer’s utility is affected by their neighbors’ purchase probabilities in a network. We first characterize the choice probabilities and then consider the associated personalized assortment optimization problem. Although this problem is NP-hard, we show that for star networks, the optimal assortment to the central consumer cannot be strictly larger than that without network effects; and the optimal assortment to each peripheral consumer must be a revenue-ordered assortment. Then, we propose a novel idea in which the sellers are allowed to offer “randomized assortments” to each node in the network by viewing each node as a consumer group. We show that randomized assortments may further increase the revenue, and for general network setting, under certain conditions, the optimal assortment must be a combination of two adjacent revenue-ordered assortments. Finally, we study the associated optimal pricing problem and develop structural properties and efficient algorithms.
Competing with Theories: Using Awareness and Confidence to Secure Resources and Rents
Authors: Ehrig Timo , Zenger Todd
Published: November 2024

An assumption of factor market efficiency is often used to grant primacy to firms’ existing unique and valuable resources as the source of economic rents. But this assumption is difficult to reconcile with observed market outcomes. For instance, five of the six companies with the highest global market capitalization in 2022 were upstarts in their industries with few resources at their origins. More surprising, three of these entrants were assisted by incumbents with vastly superior resources in assembling the resources they required. In this paper we explore how entrants compete with theories to secure resources from incumbents and capture rents. We introduce a modeling approach in which theories with causal logic generate awareness of valuable potential future states and shape the beliefs about payoffs and probabilities associated with these states. We combine work in the theory-based view and value capture theory to distinguish among three distinct sources of economic rents that are potentially available to entrants: awareness rents, confidence rents, and resource rents. We explore the circumstances under which these three types of rents are available. By exploring the role of theories and awareness in value creation and capture, our paper seeks to deepen our understanding of how entrants both attract resources and secure rents.

This study assessed the fluctuations of two key indexes - Fulton and Clark indexes - in evaluating the nutritional status and health of Mystus albolineatus at two different sampling sites within the Hau River basin, Mekong Delta. A total of 597 specimens comprising 307 females and 290 males were collected from Cai Rang (Can Tho) and Long Phu (Soc Trang) from January to December (2023). The results indicated that both indexes were not influenced by sex or sampling site but varied significantly according to season and month. The Fulton index was significantly higher during the dry season (1.53±0.03 SE) compared to the wet season (1.35±0.04 SE, F=14.06, p<0.001). Similarly, the Clark index was significantly higher during the dry season (0.84±0.02 SE) compared to the wet season (0.67±0.02 SE, F=30.94, p<0.001). This suggests a better nutritional status during the dry season for this species. The findings played important information regarding the nutritional status and health of Mystus albolineatus, contributing to managing and conserving fishery resources in the Mekong Delta.

The vendors of pet snakes in exhibitions do not use a hide box in their enclosures, so there is a risk of inappropriate handling by customers. This study investigated the effects of enrichment (a hide box) and handling duration (5 and 10 minutes) on the behavior of captive corn snakes (n=8). During period 1 (weeks 1-4), snakes were kept in standard enclosures with sawdust and a water bowl. In period 2 (weeks 5-8), a hide box was added. An instantaneous time and scan sampling observation technique was used. Observations were conducted two hours per week during the 1st -3rd week of each period, recording the general behavior and body postures of the snakes every 5 minutes. In the 4th week of each period, the snakes were handled for 5 minutes on Saturday and 10 minutes on Sunday, with their behavior recorded for 5 minutes post-handling. Results showed that adding a hide box significantly decreased locomotion, digging and soaking (P<0.05). The snakes frequently used the hide box and were tightly coiled 25.61% of the observation time. However, the other body postures showed no significant differences between periods. There were no significant effects of periods and handling duration on behavioral duration, except that a 10-minute handling in period 2 made the snakes more inactive (P<0.05). After a 5-minute handling, the snakes were more active than after a 10-minute handling (P<0.05). In conclusion, adding a hide box to enclosures allowed snakes to exhibit their natural behavior. While enrichment and handling duration did not significantly affect overall behaviors, longer handling durations under enrichment conditions did influence activity levels. Further research is needed to find clearer explanations.

This paper proposes a terahertz absorber based on a U-shaped metal patch that exhibits both narrowband and wideband absorption characteristics. The absorber comprises a metal–medium–metal structure, with a U-shaped metal patch as the top layer, a lossy medium as the middle layer, and a fully covered metal base plate at the bottom. There are two narrowband absorption peaks at 1.368 THz and 2.648 THz and a broadband absorption band from approximately 4 to 5 THz. The formation of resonance frequencies was elucidated by analyzing the current and electric field distributions at the resonance frequency. The resonant mechanism of the U-shaped patterned structure was clarified using equivalent circuit models to evaluate the resonant frequencies of different absorption peaks. Subsequently, the absorber’s characteristics were examined under varying structural parameters. Dual-function terahertz absorbers are applicable in terahertz communications, imaging, and various other fields.

The metalens, a significant branch of metasurfaces, holds substantial application potential. However, it often faces issues such as chromatic aberration and narrow bandwidth. This paper compares various optimization methods for the inertia weight (ω) and learning factors (C) of the particle swarm optimization (PSO) algorithm and integrates it with the genetic algorithm (GA). After the comparison, we selected the optimized algorithm that best fits our needs to design a broadband achromatic metalens operating in the wavelength range of 1–1.25 µm. The average efficiency reached 76%, providing a valuable reference for the development and application of achromatic metalenses.

Optical communication telescopes (OCTs) on motion platforms are essential for the establishment of global-scale optical communication networks. OCTs with high pointing accuracy can reduce acquisition time and increase acquisition probability. The pointing accuracy of OCTs is influenced by mechanical structure errors, structural wobble errors, and attitude measurement errors. Existing pointing error correction models for OCTs on motion platforms have limitations in addressing these errors. In this paper, we propose an innovative, to our knowledge, stellar correction pointing model based on line-of-sight (LOS) attitude measurements on motion platforms to improve the pointing accuracy. Initially, the stellar correction model compensates for the attitude measurement errors. Then, guide angles are calculated using the LOS attitude, which eliminates the mechanical structure errors and the structural wobble errors. To validate the effectiveness of the model, we built an OCT system on a motion platform and conducted star pointing experiments. The experimental results show that, compared with the existing model, our model reduces the pointing error by 37.2%, from 24.5 to 15.37 arcsec RMS. Therefore, the stellar correction pointing model based on the LOS attitude measurements is an effective method for improving the pointing accuracy of OCTs on motion platforms.

Digital signature (DS) is an essential application of cryptography, used to certify the provenance of a message and its authenticity, guaranteeing the non-repudiation, unforgeability, and transferability of messages. However, the forthcoming advent of quantum computation poses a significant threat to classical signature schemes. A possible solution could be the introduction of novel DS schemes based on the fundamental laws of quantum physics. Recently, several quantum DS (QDS) protocols have been proposed, even relying on the exploitation of off-the-shelf quantum key distribution (QKD) solutions. However, their efficiency and large signature size, uncorrelated to the size of the message to sign, represent the main limitation in their employment in a practical scenario. A trade-off solution could be a quantum-assisted DS (QADS), where the QKD technology is exploited together with classical cryptographic functions to achieve a stronger DS scheme, more resistant even to quantum attacks. We propose a generalized quantum-assisted digital signature (G-QADS) protocol based on a hybrid system, composed by the standard Wegman-Carter Message Authentication Code (WG-MAC) together with symmetric QKD keys, to enhance the security of the DS, allowing messages with arbitrary lengths to be signed while maintaining a suitable DS length. In this work, the G-QADS process is proposed for a three-party configuration (one signer and two verifiers), where the third participant is involved in the procedure just in the case of contention between the other two parties. The G-QADS protocol is then experimentally tested to prove its resilience to forging and non-repudiation attacks, demonstrating its capability in securing the message signature (with a success probability of the attacks <10−18). The performance is experimentally tested exploiting QKD prototypes based on standard BB84 protocol with decoy states and polarization encoding, in a software-defined network (SDN) infrastructure supervised by a single SDN controller, which provides the management of both classical and quantum communication channels. The proposed solution could push the practical exploitation of QKD into a new application domain, leading to a more pervasive integration of quantum technology in realistic scenarios.

Towards growing challenges of information security and authentication, various optical techniques based on holography, diffraction, interference, metasurfaces, etc., deliver promising solutions with low energy consumption and parallel high-speed information processing. Here, we report on a new dimension–second-order coherence found in the well-known Hanbury Brown and Twiss (HBT) effect–for performing optical authentication and secret sharing. We develop a method to generate a pair of correlated phase-only masks, each of which is distributed to a shareholder and can produce a specific pattern as authentication under coherent illumination, while two secret images are encrypted in the mutual information of two masks. By combining two masks in two configurations, two secret images can be extracted through spatially cascaded display under coherent illumination and intensity correlation under incoherent illumination, respectively. Conspicuously, two extremes of coherence–spatially coherent or incoherent–will enable the encoding and decoding of two different images with the same phase masks, indicating that the first-order and second-order coherence can be two independent channels for optical cryptography just like other degrees of freedom of light (e.g., polarization). Moreover, we demonstrate a polarization-multiplexing scheme to achieve polarization-selective HBT-type optically secret-sharing with increased capacity, and this type of polarization-phase masks can be readily replaced with metasurfaces.
