Impulse-controllability of system classes of switched differential algebraic equations
Authors: Wijnbergen Paul , Trenn Stephan 
Published: August 2023

AbstractIn this paper, impulse-controllability of system classes containing switched DAEs is studied. We introduce several notions of impulse-controllability of system classes and provide a characterization of strong impulse-controllability of system classes generated by arbitrary switching signals. For a system class generated by switching signals with a fixed-mode sequence, it is shown that either almost all systems are impulse-controllable, or almost all systems are impulse-uncontrollable. Sufficient conditions for all systems in this system class to be impulse-controllable or impulse-uncontrollable are presented. Furthermore, it is observed that even if all systems in a system class are impulse-controllable, knowledge of all the switching times is generally necessary to construct an input that ensures impulse-free solutions. Consequently, it is impossible to design a controller in real time if the switching times in the future are unknown. This phenomenon can be regarded as a causality issue. Therefore, the concept of (quasi-) causal impulse-controllability is introduced, and system classes which are (quasi-) causal are characterized. Finally, necessary and sufficient conditions for a system class to be causal given some dwell-time are stated.
Integral representation and $$\Gamma $$-convergence for free-discontinuity problems with $$p(\cdot )$$-growth
Authors: Scilla Giovanni , Solombrino Francesco , Stroffolini Bianca 
Published: August 2023

AbstractAn integral representation result for free-discontinuity energies defined on the space$$GSBV^{p(\cdot )}$$GSBVp(·)of generalized special functions of bounded variation with variable exponent is proved, under the assumption of log-Hölder continuity for the variable exponentp(x). Our analysis is based on a variable exponent version of the global method for relaxation devised in Bouchitté et al. (Arch Ration Mech Anal 165:187–242, 2002) for a constant exponent. We prove$$\Gamma $$Γ-convergence of sequences of energies of the same type, we identify the limit integrands in terms of asymptotic cell formulas and prove a non-interaction property between bulk and surface contributions.
Indications for replantation and factors that predict success
Authors: Bregman Dana , Nicholson Luke 
Published: August 2023

AbstractSince the advent of replantation techniques, there has been uneven progress in terms of success—even considering whether success is defined as continued perfusion of the digit or long term functional outcomes. Early enthusiasm and success have not been maintained despite increasing familiarity with microsurgical techniques and greater understanding of how to optimize outcomes for the individual components of replantation such as tendon repair, nerve repair, and osteosynthesis. Practitioners participating in the care of patients undergoing replantation should be familiar with the history and current understanding of both the indications and contraindications for the procedure, post-operative rehabilitation, and factors contributing to functional outcomes. A review of the literature from the first publications on the topic demonstrates evolution in practice and understanding of which patients should be indicated for replantation. Indications can be considered in three broad categories: injury factors, patient factors, and care context factors. These factors intersect with one another and can inform the surgeon pre-operatively regarding the most likely outcome for a given patient. This insight is critical to discuss pre-operatively with the patient in order to make a shared decision about how to manage their injury.
Chain Dynamics in a Polyelectrolyte Solution Under Shear: A Rheological NMR Investigation
Authors: Bartosch Sascha , Kohn Benjamin , Scheler Ulrich 
Published: August 2023

AbstractRheological nuclear magnetic resonance (NMR) has been applied to study the effect of shear on the chain dynamics in a solution of a linear poly(sodium 4-styrenesulfonate). Information on the chain dynamics of poly(sodium 4-styrenesulfonate) sheared in a narrow-gap concentric double cylinder cell is inferred from the NMR transverse relaxation T2 for a concentration in the semidilute-entangled and in the concentrated regime. In the semidilute-entangled concentration enhanced relaxation is observed. In the concentrated regime signatures of a loss of entanglements are seen with increasing T2 and a decreasing fraction of the polymer showing restricted motion. The effect is enhanced when the electrostatic interaction along the polymer chain is reduced by the addition of NaCl.
Is more always better? Unveiling the impact of contributor dynamics on collaborative mapping
Authors: McGough Aylin , Kavak Hamdi , Mahabir Ron 
Published: August 2023

AbstractOpen, collaborative mapping initiatives such as OpenStreetMap, a wiki-style map of the world, continually face concerns about the reliability and authority of its data. Based on harnessing the power of millions of volunteers globally, the data production process is decentralized and reflects a mosaic of individual contributors’ skills, motivations, and experiences. Linus’ Law, a widespread assumption within open-source communities, suggests that data quality increases with the number of contributors. In this paper, we evaluate Linus’ Law as applied to the co-production of volunteered geographic information using an agent-based model and examine the effects of knowledge level, variability, and prioritization on emergent production patterns and overall data quality. Our results demonstrate how diminishing returns and the experience of contributors limit Linus’ Law as an intrinsic assessment of data quality.
Belief: What is it Good for?
Authors: MacFarlane John 
Published: August 2023

Abstract“Absolutely nothing,” say the radical Bayesians. “Simplifying decisions,” say the moderates. “Providing premises in practical reasoning,” say the epistemologists. “Coordinating with others,” say I. It is hard to see how to construct an adequate theory of rational behavior without using a graded notion of belief, such as credence. But once we have credence, what role is left for belief? After surveying some answers to this question, I will explore the idea that belief is in a different line of work altogether. Its job is not to rationalize and explain an agent’s behavior, but to track what the agent would accept as a reason. Although some philosophers have seen the connection between belief and reasons, they have tended to see reasons as part of a theory of rational action. This locates belief in the rationalizing and explaining business, where it must vie with credence. In contrast, I argue that reasons play no essential role in an account of individual rationality; they are important because we need to coordinate with others. Credence and belief thus answer to separate needs.

Abstract
Purpose
Since the introduction of the molecular definition of oligodendrogliomas based on isocitrate dehydrogenase (IDH)-status and the 1p19q-codeletion, it has become increasingly evident how this glioma entity differs much from other diffuse lower grade gliomas and stands out with longer survival and often better responsiveness to adjuvant therapy. Therefore, apart from using a molecular oligodendroglioma definition, an extended follow-up time is necessary to understand the nature of this slow growing, yet malignant condition. The aim of this study was to describe the long-term course of the oligodendroglioma disease in a population-based setting and to determine which factors affect outcome in terms of survival.

Methods
All adults with WHO-grade 2 oligodendrogliomas with known 1p19q-codeletion from five Scandinavian neurosurgical centers and with a follow-up time exceeding 5 years, were analyzed regarding survival and factors potentially affecting survival.

Results
126 patients diagnosed between 1998 and 2016 were identified. The median follow-up was 12.0 years, and the median survival was 17.8 years (95% CI 16.0–19.6).
Factors associated with shorter survival in multivariable analysis were age (HR 1.05 per year; CI 1.02–1.08, p < 0.001), tumor diameter (HR 1.05 per millimeter; CI 1.02–1.08, p < 0.001) and poor preoperative functional status (KPS < 80) (HR 4.47; CI 1.70–11.78, p = 0.002). In our material, surgical strategy was not associated with survival.

Conclusion
Individuals with molecularly defined oligodendrogliomas demonstrate long survival, also in a population-based setting. This is important to consider for optimal timing of therapies that may cause long-term side effects. Advanced age, large tumors and poor function before surgery are predictors of shorter survival.

Cartel Leniency and Settlements: A Joint Perspective
Authors: Dijkstra Peter T. , Seifert Jacob 
Published: August 2023

AbstractThis paper studies the interactions between a cartel leniency program and a settlement procedure. The EU settlement procedure gives colluding firms that do not apply for leniency an additional opportunity to cooperate with the competition authority in exchange for a reduced fine after a preliminary case has been established against them. We derive the conditions under which colluding firms apply for leniency, settle, or refuse to cooperate with the authority in equilibrium. Our policy results show that settlements can act as a complement or as a substitute to the leniency program. We also study the welfare-optimal policy and highlight a novel interdependence between the fine reductions that should be offered to leniency applicants and to settling firms.
Influence of sanitation facilities on diarrhea prevalence among children aged below 5 years in flood-prone areas of Bangladesh: a multilevel analysis
Authors: Kikuchi Michiko 
Published: August 2023

AbstractAlthough the improvement of sanitation facilities has been a major contributor to improving public health, it is not guaranteed to prevent negative health outcomes. This is especially true in areas affected by severe natural disasters, such as flooding or extreme rainfall. Previous studies have examined the association between catastrophic natural disasters and negative health outcomes. However, studies on disaster-prone areas are limited. This study focused on the impact of flood risks and examined whether the improvement of sanitation facilities would be sufficient to suppress the prevalence of diarrhea in flood-prone areas. Two secondary datasets including geodata on flood-prone areas were used for the analysis: one each was obtained from the Bangladesh Demographic and Health Survey and Bangladesh Agricultural Research Council. Two models with categorizations of sanitation facilities based on containment type and excreta flow were applied for analysis. Results showed that the severe flood-prone areas and “diffused” type of sanitation, where the feces are diffused without any containment, had significant positive associations with diarrhea prevalence; however, the interaction between them was negative. Moderate flood-prone areas had a significant positive association with diarrhea prevalence; however, the interaction with unimproved sanitation, which includes containment without clear partition from feces, was significantly negative. These findings indicate that improved sanitation or containment type of sanitation may not positively contribute to the prevention of diarrhea in these severe- and moderate-flood prone areas. The urgent need for alternative sanitation technologies should be addressed in flood-prone regions.
Impact of Bariatric Surgery in the Short and Long Term: A Need for Time-Dependent Dosing of Drugs

Published: August 2023

AbstractSparse information is available on pharmacokinetic changes of drugs over time after bariatric surgery. By reviewing the literature on the short- and long-term pharmacokinetic changes of drugs, several patterns were identified for 39 drugs. No relevant pharmacokinetic changes were identified for roughly a third of the drugs. Of the remaining drugs, levels were variable and partly unpredictable shortly after the surgery. In the long term, most of the drug levels remain altered, but in some cases they returned to preoperative values. Based on the changes and the efficacy-safety balance of each drug, clinicians may need to perform additional clinical monitoring for specific drugs, including measuring drug levels. This review provides suggestions for clinicians and pharmacists for specific time-dependent drug dosing advice.

Abstract
Background
The prevalence of type 2 diabetes mellitus (T2DM) is increasing each year and has become one of the most prominent health concerns worldwide. Patients with T2DM are prone to infectious diseases, and urinary tract infections are also widespread. Despite a comprehensive understanding of urinary tract infection (UTI), there is a lack of research regarding primary prevention strategies for asymptomatic bacteriuria (ASB).

Objective
To clarify the incidence and risk factors of asymptomatic urinary tract infection in patients with T2DM by meta-analysis to provide evidence for preventing UTI. Help patients, their families, and caregivers to identify the risk factors of patients in time and intervene to reduce the incidence of ASB in patients with T2DM. Fill in the gaps in existing research.

Study design
Meta-analyses were conducted in line with PRISMA guidelines.

Methods
Eleven databases were systematically searched for articles about ASB in T2DM, and the retrieval time was selected from the establishment of the database to February 5, 2023. Literature screening, quality evaluation, and meta-analysis were independently performed by two researchers according to the inclusion and exclusion criteria, and a meta-analysis was performed using Stata 17.0.

Results
Fourteen articles were included, including cohort and case–control studies. A meta-analysis of 4044 patients with T2DM was included. The incidence of ASB in patients with T2DM was 23.7%(95% CI (0.183, 0.291); P < 0.001). After controlling for confounding variables, the following risk factors were associated with ASB in patients with T2DM: age (WMD = 3.18, 95% CI (1.91, 4.45), I2 = 75.5%, P < 0.001), female sex (OR = 1.07, 95% CI(1.02, 1.12), I2 = 79.3%, P = 0.002), duration of type 2 diabetes (WMD = 2.54, 95% CI (1.53, 5.43), I2 = 80.7%, P < 0.001), HbA1c (WMD = 0.63, 95% CI (0.43, 0.84), I2 = 62.6,%. P < 0.001), hypertension (OR = 1.59, 95% CI (1.24, 2.04), I2 = 0%, <0.001), hyperlipidemia (OR = 1.66, 95% CI (1.27, 2.18), I2 = 0%, P < 0.001), Neuropathy (OR = 1.81, 95% CI (1.38, 2.37), I2 = 0%, P < 0.001), proteinuria (OR = 3.00, 95% CI (1.82, 4.95), I2 = 62.7%, P < 0.001).

Conclusion
The overall prevalence of ASB in T2DM is 23.7%. Age, female sex, course of T2DM, HbA1C, hypertension, hyperlipidemia, neuropathy, and proteinuria were identified as related risk factors for ASB in T2DM. These findings can provide a robust theoretical basis for preventing and managing ASB in T2DM.

Published: August 2023

AbstractWorldwide, fruit is an indispensable treasure house of nutrition for human beings, occupying a vital position of human diet. Postharvest fruit storage requires efficient antifungal agents to control Botrytis cinerea, which is a vital postharvest disease affecting fruit and leading to enormous losses. However, with the enormous abuse of existing antifungal drugs, the problem of drug-resistant fungi is imminent, making the controlling diseases caused by pathogenic fungi even more challenging. Drug repurposing is an efficient alternative method, we evaluated a well-known antifungal chemical, terbinafine, against the agricultural pathogen, B. cinerea in vitro, as a result, terbinafine showed strong antifungal activity. Furthermore, the in vivo antifungal activity of terbinafine was evaluated, the results showed that terbinafine could reduce the decay area on grapes. Terbinafine could disrupt the cell membrane integrity, increase cell membrane permeability, and eventual cell death of B. cinerea. In addition, terbinafine reduced decay incidence, and weight loss and maintained the soluble solids, titratable acidity, ascorbic acid, total phenolic, and malondialdehyde content during the storage period of grapes. Overall, terbinafine could be an antifungal preservative for postharvest table grapes fresh-keeping.

In what ways does age-differentiated leadership influence employee health?
Authors: Uhlmann Lena Marie , Karabinski Tina , Wendsche Johannes , Wegge Jürgen 
Published: August 2023

AbstractAccording to Wegge et al. (2014), leadership behavior can affect employee health in several ways. The model describes leaders (1) as actors with a direct influence on the health of employees, (2) as designers of work systems, (3) as a moderating factor (buffer/amplifier) of the effects of work requirements and resources on health, (4) as a developer of group climate and identification and (5) as direct role models for health-related behavior. In order to collect evidence for the usefulness of this multi-path model, connections between age-differentiated leadership (ADL) and health were analyzed in 947 employees of a German technology company. ADL is a management style that takes into account the particularities of mixed-age teams and also differentiates between the different needs of different age groups. It was found that better ADL (when controlling for employee-oriented leadership) is associated with fewer physical and psychological complaints (pathway 1). This relationship is mediated by the manager’s social support (path 2) and a better recreational climate in the team (path 4). Better ADL also reduced the negative effects of psychological work demands on the psychological symptoms (pathway 3).Practical Relevance: This article provides practical evidence for the multi-way model of leadership and health. Using the example of age-differentiated leadership (ADL)—with control of employee-oriented leadership—it was also found that this leadership behavior has a positive effect on the mental and physical health of employees via four different paths and should therefore be encouraged.
On-Chain Video Copy Detection Based on Swin-Transformer and Deep Hashing

Published: August 2023

AbstractIn recent years, short videos are spreading faster and become higher quality due to edge-cloud technology. People receive information gradually from graphic to video. At the same time as the number of videos spread rapidly, infringing videos are also flooding the Internet. The wild spread of infringing videos on the Internet has brought serious losses to video websites and original authors. Although video copy detection can solve such problems, the detection results are easy to be tampered with, and the detection results are hardly convincing. Based on this, this paper proposes an open, transparent and verifiable video copy detection method, which uses blockchain technology to ensure the transparency and openness of the results. In addition, this method adopts the combination of on-chain and off-chain methods to automatically perform copyright detection by invoking smart contracts on the chain. This mechanism can securely and immutably store video feature values on the blockchain, ensuring the originality of copyrighted works and the ability to verify detection results. Swin-Transformer and deep hashing are used to obtain video features off the blockchain, which can efficiently match the similarity of existing videos. The method of block comparison can greatly shorten the comparison time, which is 1/50 of the traditional comparison time. Experimental results show that this method is very effective in retrieving similar images and detecting the similarity between original and pirated videos.
Conditional mixing in deterministic chaos
Authors: WORMELL CAROLINE L. 
Published: August 2023

AbstractWhile on the one hand, chaotic dynamical systems can be predicted for all time given exact knowledge of an initial state, they are also in many cases rapidly mixing, meaning that smooth probabilistic information (quantified by measures) on the system’s state has negligible value for predicting the long-term future. However, an understanding of the long-term predictive value of intermediate kinds of probabilistic information is necessary in various physical problems, and largely remains lacking. Of particular interest in data assimilation and linear response theory are the conditional measures of the Sinai–Ruelle–Bowen (SRB) measure on zero sets of general smooth functions of the phase space. In this paper we give rigorous and numerical evidence that such measures generically converge back under the dynamics to the full SRB measures, exponentially quickly. We call this property conditional mixing. While conditional mixing typically cannot be proven from standard transfer operator theory, we will prove that conditional mixing holds in a class of generalized baker’s maps, and demonstrate it numerically in some non-Markovian piecewise hyperbolic maps. Conditional mixing provides a natural limit on the effectiveness of long-term forecasting of chaotic systems via partial observations, and appears key to proving the existence of linear response outside the setting of smooth uniform hyperbolicity.
