We present the design and deployment of a capsule endoscope via external electromagnets for locomotion in large volumes alongside its digital twin implementation based on interval type-2 fuzzy logic systems (IT2-FLSs). To perform locomotion, we developed an external mechanism comprising five external electromagnets on a two-dimensional translational platform that is to be placed underneath the patients’ bed and integrated multiple Neodymium magnets into the capsule. The interaction between the central bottom external electromagnet and the internal magnet forms a fixed body frame at the capsule center, allowing rotation. The interaction between the external electromagnets and the two internal magnets results in rotation. The elevation of the capsule is accomplished due to the interaction between the upper external electromagnet and the internal magnets. Through simulations, we model the capsule rotation as a function of torque and drive voltages. We validated the proposed locomotion approach experimentally and observed that the results are highly nonlinear and uncertain. Thus, we define a regression problem in which IT2-FLSs, capable of representing nonlinearity and uncertainty, are learned. To verify the proposed locomotion approach and test the IT2-FLS, we leverage our experimental effort to a stomach phantom and finally to an ex vivo bovine stomach. The experimental results validate the locomotion capability and show that the IT2-FLS can capture uncertainties while resulting in satisfactory prediction performance. To showcase the benefit in a clinical scenario, we present a digital twin implementation of the proposed approach in a virtual environment that can link physical and virtual worlds in real time.

In this summary of US Centers for Disease Control and Prevention (CDC) consultations with state and local health departments concerning their bronchoscope-associated investigations from 2014 through 2022, bronchoscope reprocessing gaps and exposure to nonsterile water sources appeared to be the major routes of transmission of infectious pathogens, which were primarily water-associated bacteria.

We evaluated the prevalence and treatment of asymptomatic bacteriuria (ASB) in 17 critical-access hospitals. Among 891 patients with urine cultures from September 2021 to June 2022, 170 (35%) had ASB. Also, 76% of patients with ASB received antibiotics for a median duration of 7 days, demonstrating opportunities for antimicrobial stewardship.

This article uses Statoil (Equinor since 2018) as a prism to explore some key features and concerns of Western oil companies’ evolving human rights awareness from the mid-1990s to the early 2000s. This period saw the first human rights lawsuits brought against oil companies and a gradual change in their human rights awareness. The article uses insights from the business history literature and new archival material from the oil industry to explain why business ethicists and legal scholars are wrong to argue that the relationship between business and social responsibility, on the one hand, and business and human rights, on the other, are inherently problematic and profoundly disparate due to their divergent historical origins. In so doing, the article offers a historical take on the so-called debate between business human rights (BHR) and corporate social responsibility (CSR), and it repudiates the argument that a so-called minimal understanding of human rights has hindered business from undertaking proactive human rights initiatives. Mapping onto both the business history literature and the BHR–CSR debate, the article aims for a richer understanding of the experiences and ideas that incentivized oil companies to “get serious” about human rights.

We prove a difference analogue of the celebrated Tumura–Hayman–Clunie theorem. Let f be a transcendental entire function, let c be a nonzero constant and let n be a positive integer. If f and $\Delta _c^n f$ omit zero in the whole complex plane, then either $f(z)=\exp (h_1(z)+C_1 z)$, where $h_1$ is an entire function of period c and $\exp (C_1 c)\neq 1$, or $f(z)=\exp (h_2(z)+C_2 z)$, where $h_2$ is an entire function of period $2c$ and $C_2$ satisfies

$$ \begin{align*} \bigg(\frac{1+\exp(C_2c)}{1-\exp(C_2 c)}\bigg)^{2n}=1. \end{align*} $$

We improve and expand in two directions the theory of norms on complex matrices induced by random vectors. We first provide a simple proof of the classification of weakly unitarily invariant norms on the Hermitian matrices. We use this to extend the main theorem in Chávez, Garcia, and Hurley (2023, Canadian Mathematical Bulletin 66, 808–826) from exponent $d\geq 2$ to $d \geq 1$. Our proofs are much simpler than the originals: they do not require Lewis’ framework for group invariance in convex matrix analysis. This clarification puts the entire theory on simpler foundations while extending its range of applicability.

This meta-analysis synthesized 35 English studies (130 effect sizes, N = 1,981) that employed online tasks to investigate the processing of multiword sequences (MWSs). We examined (a) to what extent MWSs enjoy a processing advantage over novel word combinations; (b) how such a processing advantage is moderated by statistical regularities (i.e., phrasal frequency, association strength), MWS type, and explicitness of experimental tasks; and (c) whether such moderating patterns differ between L1 speakers and L2 speakers. The results confirmed the processing advantage for most subtypes of MWSs, with effect sizes ranging from small to medium. For L1 speakers and L2 speakers, the processing advantage of MWSs was found across the continuum of phrasal frequency and association strength and varied. Interestingly, task explicitness moderated the processing advantage of MWSs but only for L2 speakers. Taken together, our results shed light on the understanding of MWSs as well as directions for future research.

Despite private enterprises dominating China's labour market, college-educated workers are still highly concentrated in the state sector. Using data from the Chinese College Student Survey, we find that 64 per cent of students in the sample expressed a strong preference for state sector employment. We also identify several factors associated with receiving job offers from the state sector, including being male, holding urban hukou status, being a member of the CCP, performing well on standardized tests, attending elite universities and having higher household income or high-status parental backgrounds. These findings suggest that despite China's economic transition, the private sector may still struggle to attract highly educated workers.

We investigate the geometry of codimension one foliations on smooth projective varieties defined over fields of positive characteristic with an eye toward applications to the structure of codimension one holomorphic foliations on projective manifolds.

The Government of the Islamic Republic of Afghanistan (GIRoA), in power during 2002–2021, initiated the process of instituting community-based forest governance and building local capacity for natural resource management. These efforts coincided with the presence of international security forces and the mobilization of civil society organizations, and they were in response to community aspirations to protect and restore often degraded local forests. Legislation was passed to enable forest protection and management, including a provision to encourage participatory management by local community user groups organized as Forest Management Associations (FMAs). By the end of the GIRoA era, c. 20 registered FMAs were operating with c. 400 others in various stages of development across Afghanistan. Our analysis of relevant policy documents revealed that the policy framework developed during the GIRoA era scores favourably on the ideal criteria for community-based resource management. Despite the change in political administration with the inception of the current Islamic Emirate of Afghanistan regime, the influence of the GIRoA era serves as a starting point and may have enduring influences on rural communities in Afghanistan and the natural resources that support them. Anecdotal evidence suggests that community-based forest management may persist under the current national leadership despite international isolation and funding constraints. The model developed in Afghanistan may be relevant to other fragile states, especially in contexts where rural forest-dependent communities have strong local institutions, such as shuras, and where forests are not prone to heavy extraction pressure.

This article examines aspirational laws in a randomized field experiment. We analyze the impact of an unenforced public smoking ban on individual behavior and attitudes. The findings indicate that aspirational laws, like public smoking bans, can make rights holders sensitive to behavior that violates their rights, irrespective of the material consequences of infringements and their personal views about the law. The results present a mixed position in the debate between rights-based social movement lawyering and critics of hollow rights. On the one hand, aspirational laws can create unforeseen social frictions when rights are declared, but their implementation and enforcement are ineffective. On the other hand, aspirational laws may also have self-fulfilling potential. Due to the adverse experience of rule breaking, rights holders may seek enforcement and compliance even if the law fails to influence public beliefs.

Although legal transplants are a most fertile source of legal development, a failure to adapt their methods to local traditions and cultures before putting them into practice often results in the loss of indigenous legal cultures. This article examines environmental jurisprudence in Nigeria. It aims to determine whether the failure of these laws to curb the trend of unsustainable natural resource use in the country is traceable to the indigenous legal cultures of sustainability that were lost in the process of transplanting colonial ideologies into the Nigerian legal system. The article submits that neglecting the innate standards of sustainability in Nigeria's environmental law-making (a practice adopted since the period of colonization) has made the extant laws on natural resource sustainability largely ineffective. It recommends reworking some of the laws to reflect the lost traditions and notes the cultural imperative for natural resource sustainability.

Capitalist ideas of productivity became central to medicine under slavery. They shaped how physicians treated enslaved patients, crafted a scientific basis for medicine, and conceived of themselves as professionals. Between the late-eighteenth-century and the mid-nineteenth-century, white male physicians in Louisiana and Cuba distinguished themselves from other healers: first, by aligning with Spanish colonialism, and then, by making themselves essential to a new form of plantation management that used clock-time discipline, hierarchical divisions of labor, and complex accounting systems. These technologies helped planters track the hours and days each enslaved person spent working, eating, sleeping, birthing, suffering from sickness and injuries, and recovering. This in turn enabled precise interpretations of enslaved health in terms of productivity, which was primarily measured in work time and the number of commodities produced. Physicians, who were seeking a rigorous intellectual foundation for medical knowledge production, latched onto planter methods of calculating and controlling enslaved health. One of those methods was what planters and physicians called “sick time,” which was an allotment of time away from work intended to manage illness enough for enslaved people to return to work. However, as physicians used plantation management to cast an air of scientific accuracy over their knowledge, enslaved people reconfigured their own medical practices to make themselves less visible and countable. Fugitive practices involving trees, animals, and natural springs helped enslaved people to heal by taking their own forms of sick time.
