Breaking Malus’ law: Highly efficient, broadband, and angular robust asymmetric light transmitting metasurface

High efficiency, broad bandwidth, and robust angular tolerance are key considerations in photonic device design. Here, a few‐layer, asymmetric light transmitting metasurface that simultaneously satisfies all the above requirements is reported. The metasurface consists of coupled metallic sheets. It has a measured transmission efficiency of 80%, extinction ratio of 13.8 dB around 1.5 μm, and a full width half maximum bandwidth of 1.7 μm. It is as thin as 290 nm, has good performance tolerance against the angle of incidence and constituent nano‐structure geometry variations. This work demonstrates a practical asymmetric light transmission device with optimal performance for large scale manufacturing.
Long-term oncological and surgical outcomes after Video Endoscopic Inguinal Lymphadenectomy (VEIL) in patients with penile cancer

ABSTRACT Objective: To report outcomes from the largest multicenter series of penile cancer patients undergoing video endoscopic inguinal lymphadenectomy (VEIL). Materials and Methods: Retrospective multicenter analysis. Authors of 21 centers from the Penile Cancer Collaborative Coalition-Latin America (PeC-LA) were included. All centers performed the procedure following the same previously described standardized technique. Inclusion criteria included penile cancer patients with no palpable lymph nodes and intermediate/high-risk disease and those with non-fixed palpable lymph nodes less than 4 cm in diameter. Categorical variables are shown as percentages and frequencies whereas continuous variables as mean and range. Results: From 2006 to 2020, 210 VEIL procedures were performed in 105 patients. Mean age was 58 (45-68) years old. Mean operative time was 90 minutes (60-120). Mean lymph node yield was 10 nodes (6-16). Complication rate was 15.7%, including severe complications in 1.9% of procedures. Lymphatic and skin complications were noted in 8.6 and 4.8% of patients, respectively. Histopathological analysis revealed lymph node involvement in 26.7% of patients with non-palpable nodes. Inguinal recurrence was observed in 2.8% of patients. 10y- overall survival was 74.2% and 10-y cancer specific survival was 84.8%. CSS for pN0, pN1, pN2 and pN3 were 100%, 82.4%, 72.7% and 9.1%, respectively. Conclusion: VEIL seems to offer appropriate long term oncological control with minimal morbidity. In the absence of non-invasive stratification measures such as dynamic sentinel node biopsy, VEIL emerged as the alternative for the management of non-bulky lymph nodes in penile cancer.
A Dilated Pore of Winer in a Young Iberian Lynx (Lynx pardinus)

Abstract A 1.5-year-old male Iberian lynx born in captivity presented with a 2.2 cm exophytic nodular alopecic mass at the left tarsus medial aspect, before being released into the wild. The lesion had keratinised material protruding through a 1.2 cm pore, forming a cutaneous horn. Histopathology revealed a cystic dermo-epidermal lesion lined by psoriasiform hyperplasia of the epithelium, thicker at the base of the cyst, together with abrupt to progressive keratinization and keratin pearls. The central cystic cavity was filled with fibrillary keratin and ghost cells. Immunohistochemistry for pan-cytokeratin showed strong positive immunolabeling in the hyperplastic epithelium and a weaker immunolabeling at the content of the cyst. A final diagnosis of a Dilated Pore of Winer was made. This paper is the first reported case of a DPW in a lynx and a wild felid.
Public campaign financing’s effects on judicial legitimacy: Evidence from a survey experiment

Although judicial elections are considered a method of keeping state courts—otherwise insulated from public pressure—accountable, the private financing of judicial campaigns has been met with significant criticism. In particular, the perception that campaign contributions can buy favorable case outcomes for contributors to judicial candidates may pose problems for judicial legitimacy. While some scholars and advocacy groups have advanced proposals which seek to eliminate private financing from judicial elections, research has yet to demonstrate a link between the public’s evaluations of a court’s legitimacy and the campaign financing system the state employs. In this paper, we present the results of a survey experiment that examines the public’s evaluations of judicial legitimacy under different campaign financing schemes. We find evidence supportive of our core hypothesis: respondents viewed courts with publicly financed elections as more legitimate than those with privately financed elections. This study helps to reinforce the viability of public financing by empirically demonstrating that the public views a state supreme court elected using the public financing model as more legitimate and less susceptible to donor pressure than one selected using privately financed models.
Risk Factors for Rotator Cuff Repair Failure and Reliability of the Rotator Cuff Healing Index (RoHI) in Thai Patients: Comparison of the RoHI With a Modified Scoring System

Background: The success rate of surgical treatment for rotator cuff (RC) tear ranges from 16% to 94%. The Rotator Cuff Healing Index (RoHI) is a system for predicting failure after RC repair and is based on a combined score of factors, including age, anteroposterior (AP) tear size, tendon retraction, fatty infiltration of the infraspinatus muscle, bone mineral density (BMD), and level of work activity. Purpose: To determine the factors leading to RC repair failure in a Thai population, to test the reliability of the RoHI in this population, and to compare the RoHI with a modified RoHI (m-RoHI) based on the factors for repair failure as determined. Study Design: Case-control study; Level of evidence, 3. Methods: This study included 133 Thai patients who underwent arthroscopic RC repair between February 2012 and February 2021. Postoperative magnetic resonance imaging was performed at 6 to 24 months to evaluate RC healing. Variables that might affect failure rates were evaluated, including demographic characteristics, AP tear size and retraction, radiographic measurements, and magnetic resonance imaging findings. The m-RoHI was created using factors that significantly predicted repair failure on multivariate analysis. The area under the receiver operating characteristic curve was calculated to determine the reliability of the RoHI and to compare the reliability of the RoHI and m-RoHI to predict failure rates. Results: Multivariate logistic regression analysis revealed that body mass index ≥23 (adjusted odds ratio [OR], 9.02; P = .034), high work activity (adjusted OR, 19.53; P = .008), AP tear size ≥2.5 cm (adjusted OR, 19.04; P = .001), and a retraction size of 2 to <3 cm (adjusted OR, 20.36; P = .013) were the independent factors that predicted repair failure in our population. BMD was not independently predictive of repair failure. We used these 4 significant independent factors to generate the m-RoHI. The area under the curve of the final adjusted m-RoHI was slightly improved as compared with the original RoHI, but this difference was not significant (0.827 [95% CI, 0.741-0.913] vs 0.780 [95% CI, 0.686-0.875], respectively; P = .447). Conclusion: The m-RoHI had a similar predictive value for repair failure to the original RoHI in our study population, but it did not require obtaining BMD. The m-RoHI may be useful in populations where BMD is not routinely obtained.
A new approach to controlling an active suspension system based on reinforcement learning

Active suspension provides better vehicle control and safety on the road with optimal driving comfort compared to passive suspension. Achieving this requires a good control system that can adapt to any environment. This article uses a deep reinforcement learning method to develop an optimal neural network that meets the comfort requirements according to ISO 2631-5 standards. The algorithm trains the agent without any prior knowledge of the environment. Various simulations were performed, and the results were validated with the literature and the standard until the appropriate reward function was found. Simple and consistent road profiles were used while maintaining constant system parameters during training. The results show that suspension based on deep reinforcement learning reduces vehicle body acceleration and improves ride comfort without sacrificing suspension deflection and dynamic tire loading. The controller expects the RMS value of the acceleration to be 0.228 with a minimum overrun of the suspended mass.
Sharing Feelings and User Engagement on Twitter: It’s All About Me and You

This study explores how the expression of feelings and the use of personal pronouns on Twitter are associated with user engagement. Unlike most previous studies which focused on the types of emotions that generate user engagement, it uses the volume-control model, which also considers the social dimension of power. Looking at the usage of pronouns, it examines the balance achieved between popular messages that target larger groups and personalized messages that target smaller groups and individuals. The findings show that there is a significant difference between the motivation to share (retweet) and to reply to a message. Users on Twitter tend to retweet messages with popular characteristics, addressing larger groups with positive feelings. On the other hand, replies were associated with more personalized messages and a greater use of negative feelings. Users with more followers and friends presented a balance between popularization and personalization techniques, as their tweets were associated with higher customization of the messages to specific groups yet avoided negative feelings.
Incidence of Early Adverse Events After Tibial Tubercle Osteotomy

Background: Tibial tubercle osteotomy (TTO) is a commonly utilized surgical procedure for the treatment of patellofemoral instability. Although midterm and long-term outcomes are known, perioperative complications have not been consistently reported. Purpose: To identify the incidence and predictors of adverse events in the first 90-day perioperative period after TTO. Study Design: Case series; Level of evidence, 4. Methods: Patients undergoing primary TTO between January 1, 2010, and December 31, 2019, were included. Readmissions in the first 90 days after surgery were collected, and data were collected for the following variables: age, sex, smoking status, body mass index, laterality, preoperative diagnosis, presence of trochlear dysplasia, tourniquet use, TTO procedure, tibial tubercle distalization, trochleoplasty, chondral procedure, number of screws, and use of an epidural catheter. Predictors of readmission for any reason were identified using multivariable logistic regression analysis. Results: A total of 345 TTO procedures were included in the final analysis. The incidence of readmissions for any reason was 20.6% (71/345). The most common reason for readmission was postoperative pain (26/345 [7.5%]), followed by wound complications (19/345 [5.5%]) and epidural catheter–related complications (overall: 16/345 [4.6%]; specific: 16/167 [9.6%]. The incidence of major complications was 2.0% (7/345). The number of patients with each major complication was as follows: 1 for deep vein thrombosis, 2 for pulmonary embolism, 1 for septic arthritis, 1 for tibial tubercle fracture, and 2 for loss of fixation. Female sex and smoking were associated with readmission for pain. Conclusion: The incidence of major complications after TTO was very low (2.0%), but 20.6% of cases required readmission, primarily for an indwelling epidural catheter (3.5%) and postoperative pain (7.5%). Concomitant soft tissue procedures and the number of screws were associated with readmission after TTO. Utilizing individualized postoperative pain management and preoperative discussions about expected pain may help to avoid readmission for pain after TTO.
The More I Have Fun, the More I Experience Life Satisfaction: Gender Moderated and Engagement-mediated Model of Life Satisfaction

This study aimed to investigate the impact of workplace fun on life satisfaction through employee engagement in a gender interaction effect model. It was argued that workplace fun has a positive influence on life satisfaction through increased employee engagement. Moreover, gender effects were also tested in the relationships. This study was quantitative in nature. Under a cross-sectional study approach, data of 238 respondents collected from service sector employees were analyzed. Findings supported the argument that workplace fun leads to an improved sense of life satisfaction when individuals experience a positive state of mind and engagement at work. Moreover, fun leading to improved life satisfaction was higher among males than females. These findings implied that a fun attitude may have an indirect role in improving the life satisfaction of engaged employees suggesting that HR professionals need not seek workplace fun as a coercive practice. This study contributed to the literature on the use of workplace fun in improving life satisfaction. It also explained employee engagement as an underlying psychological mechanism that connects workplace fun with life satisfaction.
Indexicals and Names in Proverbs

Abstract This paper offers an analysis of indexical expressions and proper names as they are used in proverbs. Both indexicals and proper names contribute properties rather than objects to the propositions expressed when they are used in sentences interpreted as proverbs. According to the proposal, their contribution is accounted for by the mechanism of descriptive anaphora. Indexicals with rich linguistic meaning, such as ‘I’, ‘you’ or ‘today’, turn out to be cases of the attributive uses of indexicals, i.e. uses whose contribution relies on the linguistic meaning of the word. Third person pronouns, names of locations as well as surnames are analyzed as non-attributive descriptive uses.
Influence and Improvisation: Participatory Disinformation during the 2020 US Election

The 2020 US election was accompanied by an effort to spread a false meta-narrative of widespread voter fraud. This meta-narrative took hold among a substantial portion of the US population, undermining trust in election procedures and results, and eventually motivating the events of 6 January 2021. We examine this effort as a domestic and participatory disinformation campaign in which a variety of influencers—including hyperpartisan media and political operatives—worked alongside ordinary people to produce and amplify misleading claims, often unwittingly. To better understand the nature of participatory disinformation, we examine three cases of misleading claims of voter fraud, applying an interpretive, mixed method approach to the analysis of social media data. Contrary to a prevailing view of such campaigns as coordinated and/or elite-driven efforts, this work reveals a more hybrid form, demonstrating both top-down and bottom-up dynamics that are more akin to cultivation and improvisation.
Stock Return Synchronicity and Profitability: Evidence from India

The current research article studies the stock return synchronicity (SYNCH) and profitability for Indian firms. SYNCH is measured using the value of R2 calculated from the market model for the sample firms. The market model runs regressions of individual stock returns with the Nifty index return. The quantile regression model is run to study the SYNCH and profit after tax (PAT). In addition, the SYNCH and its relation with PAT for low-quantile firms are compared to the SYNCH of high-quantile firms. After controlling for relevant variables, the quantile regression results provide evidence that SYNCH is related to PAT. The reported results also provide evidence that the lower quantile firms differ from higher quantile firms in terms of the impact of PAT on SYNCH.
Can ❤s Change Minds? Social Media Endorsements and Policy Preferences

We investigate the effect of social media endorsements (likes, retweets, shares) on individuals’ policy preferences. In two pre-registered online experiments (N = 1,384), we exposed participants to non-neutral policy messages about the COVID-19 pandemic (emphasizing either public health or economic activity as a policy priority) while varying the level of endorsements of these messages. Our experimental treatment did not result in aggregate changes to policy views. However, our analysis indicates that active social media users did respond to the variation in engagement metrics. In particular, we find a strong positive treatment effect concentrated on a minority of individuals who correctly answered a factual manipulation check regarding the endorsements. Our results suggest that though only a fraction of individuals appear to pay conscious attention to endorsement metrics, they may be influenced by these social cues.
Making Sense of Responsibility: A Semio-Ethic Perspective on TikTok’s Algorithmic Pluralism

Utilizing the data collected from 40 in-depth interviews, this study explores: How do users perceive social media platforms’ responsibility in designing algorithms? What do users perceive as diverse or similar in the content generated by algorithmic recommendation systems? The analysis discusses and evaluates the tension between (a) how the platform’s algorithm feeds users similar videos that they highly appreciate and, inversely, (b) how the recommendation of similar videos might limit the diversity of content to which the user is exposed. The analysis adopts a semio-ethic framework to understand why algorithmic platforms like TikTok are perceived to be so efficient in promoting an apparent perception of inclusivity while deliberately erasing alterity and promoting universal sameness. Although videos recommended by TikTok might appear to satisfy computational criteria of diversity, the outcome masks the absence of algorithmic pluralism. The algorithm generates socially desirable videos to allow users to feel comfortable in their in-group. In other words, recommended videos perpetuate a digital form of conformism in a conscious attempt to create the illusion of a more plural community. Advancing the study of algorithmic pluralism is therefore crucial to evaluate the extent to which plurality is understood by users, and what assumptions and ethics underpin the cultures that foster algorithmic recommendation design.
Testing the dysregulation of goal and activity identification hypothesis on mental health outcomes: The moderating effect of psychological flexibility

The objective of this study is to test the dysregulation of goal/activity identification hypothesis and the role of psychological flexibility within it. A nonclinical sample of 247 adults completed the Personalized Psychological Flexibility Index (PPFI) and DASS-21. Participants' goal on the PPFI were categorized into abstract or concrete. The moderating effect of psychological flexibility on the relationship between goal abstraction and stress, depression and anxiety were examined. These relationships were explored using specific dimensions of psychological flexibility: harnessing, avoidance and acceptance. A significant interaction was found between psychological flexibility and goal abstraction on stress. Individuals who stipulated an abstract goal and had lower levels of psychological flexibility had significantly higher levels of stress. This relationship was not evident for concrete goals. These findings did not emerge when examining specific dimensions of psychological flexibility suggesting that multiple facets of psychological flexibility contribute to these findings. Harnessing was, however, unique. Individuals with a concrete goal and higher levels of harnessing had significantly higher stress. This study provides preliminary findings regarding the influence of psychological flexibility within the dysregulation of goal/action identification hypothesis. Future research, particularly in clinical samples is needed to confirm these associations and their combined role as a transdiagnostic process.
Zero-Mode Waveguide Nanowells for Single-Molecule Detection in Living Cells

Single-molecule fluorescence imaging experiments generally require sub-nanomolar protein concentrations to isolate single protein molecules, which makes such experiments challenging in live cells due to high intracellular protein concentrations. Here, we show that single-molecule observations can be achieved in live cells through a drastic reduction in the observation volume using overmilled zero-mode waveguides (ZMWs - subwavelength-size holes in a metal film). Overmilling of the ZMW in a palladium film creates a nanowell of tunable size in the glass layer below the aperture, which cells can penetrate. We present a thorough theoretical and experimental characterization of the optical properties of these nanowells over a wide range of ZMW diameters and overmilling depths, showing an excellent signal confinement and a five-fold fluorescence enhancement of fluorescent molecules inside nanowells. ZMW nanowells facilitate live-cell imaging, as cells form stable protrusions into the nanowells. Importantly, the nanowells greatly reduce cytoplasmic background fluorescence, enabling detection of individual membrane-bound fluorophores in the presence of high cytoplasmic expression levels, which could not be achieved with TIRF microscopy. Zero-mode waveguide nanowells thus provide great potential to study individual proteins in living cells. Graphical abstract
Visual features are processed before navigational affordances in the human brain

To navigate through their immediate environment humans process scene information rapidly. How does the cascade of neural processing elicited by scene viewing to facilitate navigational planning unfold over time? To investigate, we recorded human brain responses to visual scenes with electroencephalography (EEG) and related those to computational models that operationalize three aspects of scene processing (2D, 3D, and semantic information), as well as to a behavioral model capturing navigational affordances. We found a temporal processing hierarchy: navigational affordance is processed later than the other scene features (2D, 3D, and semantic) investigated. This reveals the temporal order with which the human brain computes complex scene information and suggests that the brain leverages these pieces of information to plan navigation.
