Block-encoding dense and full-rank kernels using hierarchical matrices: applications in quantum numerical linear algebra
Authors: Nguyen Quynh T. , Kiani Bobak T. , Lloyd Seth
Published: December 2022

Many quantum algorithms for numerical linear algebra assume black-box access to a block-encoding of the matrix of interest, which is a strong assumption when the matrix is not sparse. Kernel matrices, which arise from discretizing a kernel function k(x,x′), have a variety of applications in mathematics and engineering. They are generally dense and full-rank. Classically, the celebrated fast multipole method performs matrix multiplication on kernel matrices of dimension N in time almost linear in N by using the linear algebraic framework of hierarchical matrices. In light of this success, we propose a block-encoding scheme of the hierarchical matrix structure on a quantum computer. When applied to many physical kernel matrices, our method can improve the runtime of solving quantum linear systems of dimension N to O(κpolylog⁡(Nε)), where κ and ε are the condition number and error bound of the matrix operation. This runtime is near-optimal and, in terms of N, exponentially improves over prior quantum linear systems algorithms in the case of dense and full-rank kernel matrices. We discuss possible applications of our methodology in solving integral equations and accelerating computations in N-body problems.
Stakeholder-accountability model for artificial intelligence projects
Authors:   Maxmetrics, Heidelberg, Germany, Miller Gloria J.
Published: December 2022

Aim/purpose – This research presents a conceptual stakeholder accountability model for mapping the project actors to the conduct for which they should be held accountable in artificial intelligence (AI) projects. AI projects differ from other projects in important ways, including in their capacity to inflict harm and impact human and civil rights on a global scale. The in-project decisions are high stakes, and it is critical who decides the system’s features. Even well-designed AI systems can be deployed in ways that harm individuals, local communities, and society. Design/methodology/approach – The present study uses a systematic literature review, accountability theory, and AI success factors to elaborate on the relationships between AI project actors and stakeholders. The literature review follows the preferred reporting items for systematic reviews and meta-analyses (PRISMA) statement process. Bovens’ accountability model and AI success factors are employed as a basis for the coding framework in the thematic analysis. The study uses a web-based survey to collect data from respondents in the United States and Germany employing statistical analysis to assess public opinion on AI fairness, sustainability, and accountability. Findings – The AI stakeholder accountability model specifies the complex relationships between 16 actors and 22 stakeholder forums using 78 AI success factors to define the conduct and the obligations and consequences that characterize those relationships. The survey analysis suggests that more than 80% of the public thinks AI development should be fair and sustainable, and it sees the government and development organizations as most accountable in this regard. There are some differences between the United States and Germany regarding fairness, sustainability, and accountability. Research implications/limitations – The results should benefit project managers and project sponsors in stakeholder identification and resource assignment. The definitions offer policy advisors insights for updating AI governance practices. The model presented here is conceptual and has not been validated using real-world projects. Originality/value/contribution – The study adds context-specific information on AI to the project management literature. It defines project actors as moral agents and provides a model for mapping the accountability of project actors to stakeholder expectations and system impacts. Keywords: accountability, artificial intelligence, algorithms, project management, ethics. JEL Classification: C33, M15, O3, O32, O33, Q55.

Published: December 2022

The research aims to analyze the governance of economic philosophy by analyzing the relationship between the economic constitution and the philosophical-ideological reflection of Pancasila in critical argumentation. Economic globalization requires countries to adapt. In practice, the adaptation process can lead to the manifestation of personal and group interests, even if it is not in accordance with the economic needs of the people (Èernius, 2012). The anticipation is that the government will emphasize the position of Pancasila as the main catalyst in the economic constitution. The study was conducted using a normative juridical approach with selected sources of legal information utilized. The analysis technique was conducted using a qualitative design. The results of the study found that the economic constitution has a relationship with philosophical reflections in the form of the basic philosophy of Indonesia’s economic development and conformity with the ideological reflection of Pancasila as the state ideology (Sinaga & Putri, 2021). Moreover, the economic constitution as a philosophical-ideological reflection of Pancasila is realized through the conception of an economic constitution with a religious perspective, an economic constitution reflecting the national identity, a people-based economic constitution, and an economic constitution aimed at improving welfare.

Published: December 2022

The bottled water sector in Greece exhibits particular characteristics. After a downturn caused by the COVID-19 pandemic, investments are being made and strategic partnerships are developing, aiming both to increase their competitiveness and to choose the proper strategy for their development. On the other hand, competitiveness is a concept widely used and for that reason has occupied the literature a lot (Fischer & Schornberg, 2007). As a result, it holds great importance to identify and assess the factors that affect competitiveness, performing as a tool for the choice of the proper strategy (Chikán, Czakó, Kiss-Dobronyi, & Losonci, 2022). Of the two main ways for the competitiveness estimation, one with Michael Porter’s diamond and the other one with the use of financial indexes, the second one was selected for this paper. All the Greek bottled water manufacturing firms which published their annual balance sheets for the 2016–2020 period were studied and used for the creation of variables. Several economic parameters are studied to determine competitiveness, where market share and profitability account for the most. According to the results, profits, sales, and loans contribute significantly to competitiveness, playing a major role in the determination of strategies that specific firms may follow.
Quantifying net community production and calcification at Station ALOHA near Hawai’i: Insights and limitations from a dual tracer carbon budget approach

Published: December 2022

A budget approach is used to disentangle drivers of the seasonal mixed
layer carbon cycle at Station ALOHA (A Long-term Oligotrophic Habitat
Assessment) in the North Pacific Subtropical Gyre (NPSG). The budget
utilizes data from the WHOTS (Woods Hole - Hawaii Ocean Time-series
Site) mooring, and the ship-based Hawai‘i Ocean Time-series (HOT) in the
North Pacific Subtropical Gyre (NPSG), a region of significant oceanic
carbon uptake. Parsing the carbon variations into process components
allows an assessment of both the proportional contributions of mixed
layer carbon drivers, and the seasonal interplay of drawdown and supply
from different processes. Annual net community production reported here
is at the lower end of previously published data, while net community
calcification estimates are 4- to 7-fold higher than available sediment
trap data, the only other estimate of calcium carbonate export at this
location. Although the observed seasonal cycle in dissolved inorganic
carbon (DIC) in the NPSG has a relatively small amplitude, larger fluxes
offset each other over an average year, with major supply from physical
transport, especially lateral eddy transport throughout the year and
entrainment in the winter, and biological carbon uptake in the spring.
Gas exchange plays a smaller role, supplying carbon to the surface ocean
between Dec-May, and outgassing in Jul-Oct. Evaporation-precipitation
(E–P) is variable with precipitation prevailing in the first- and
evaporation in the second half of the year. The observed total
alkalinity signal is largely governed by E–P, with a somewhat stronger
net calcification signal in the wintertime.

Published: December 2022

OBJECTIVE

To determine whether individuals with type 1 diabetes (T1D) who develop any retinopathy at any time prior to 5 years of diabetes duration have an increased subsequent risk for further progression of retinopathy or onset of proliferative diabetic retinopathy (PDR), clinically significant macular edema (CSME), diabetes-related retinal photocoagulation, or anti-vascular endothelial growth factor injections. Additionally, to determine the influence of HbA1c and other risk factors in these individuals.

RESEARCH DESIGN AND METHODS

Diabetic retinopathy (DR) was assessed longitudinally using standardized stereoscopic seven-field fundus photography at time intervals of 6 months to 4 years. Early-onset DR (EDR) was defined as onset prior to 5 years of T1D duration. Cox models assessed the associations of EDR with subsequent risk of outcomes.

RESULTS

In unadjusted models, individuals with EDR (n = 484) had an increased subsequent risk of PDR (hazard ratio [HR] 1.51 [95% CI 1.12, 2.02], P = 0.006), CSME (HR 1.44 [1.10, 1.88], P = 0.008), and diabetes-related retinal photocoagulation (HR 1.48 [1.12, 1.96], P = 0.006) compared with individuals without EDR (n = 369). These associations remained significant when adjusted for HbA1c, but only the association with PDR remained significant after adjustment for age, duration of T1D, HbA1c, sex, systolic/diastolic blood pressure, pulse, use of ACE inhibitors, albumin excretion rate, and estimated glomerular filtration rate (HR 1.47 [95% CI 1.04, 2.06], P = 0.028).

CONCLUSIONS

These data suggest that individuals with any sign of retinopathy within the first 5 years of T1D onset may be at higher risk of long-term development of advanced DR, especially PDR. Identification of early-onset DR may influence prognosis and help guide therapeutic management to reduce the risk of future visual loss in these individuals.

Published: December 2022

A saúde do profissional exerce influência significativa na sua qualidade de vida, satisfação e desempenho laboral. Com isso, muitas situações de trabalho podem trazer riscos à saúde, dentre os quais, os danos relacionados ao trabalho. Desta forma, tanto o trabalhador quanto a organização em geral, devem oferecer ações de diagnóstico, prevenção e promoção da saúde física e mental de todo o sistema de trabalho. Esse artigo tem o objetivo de verificar a relação entre o suporte organizacional percebido pelos trabalhadores e a avaliação dos danos relacionados ao trabalho. Participaram da pesquisa 228 trabalhadores, com idade acima de 18 anos, homens e mulheres, do setor público e privado. Responderam à Escala de Percepção de Suporte Organizacional (EPSO), à Escala de Avaliação dos Danos Relacionados ao Trabalho (ADRT) e aos dados sociodemográficos por meio eletrônico através do Google forms. Observou-se que as escalas EPSO e ADRT apresentaram indicadores psicométricos confiáveis e com base numa correlação de Pearson, o suporte organizacional correlacionou-se, negativa e significativamente, EADRT e suas respectivas dimensões (físico, psicológico e social). Entende-se que, na concepção dos trabalhadores, quanto maior for o apoio (suporte) que a organização oferecer, menor a chance de que eles apresentem adoecimentos mais graves no ambiente laboral. Com base nos resultados, destaca-se a necessidade de programas de intervenção multiprofissionais com recursos humanos desenvolvidos por e dentro da organização com o objetivo de prevenção, diagnóstico e promoção da saúde dos seus trabalhadores.

There is described the influence of polyethylenimine globule structure on complexation with copper (II), nickel (II) and cobalt (II) ions. There are determined the values of the coordination number with the change of the pH of the solution for the complexes of ethylenediamine, diethylenetriamine and polyethylenimine with metal ions. It is investigated that the complexation of these metal ions with low molecular weight amines passes through three stages and with PEI through two stages. It is shown that the content of free nitrogen atoms in PEI, which do not react with metal ions, increases with increasing concentration of PEI in solution. The number of monomer units associated with metal ions depends on the size of the globule of the macromolecule, as well as the reaction process. The complexation reaction in solution is determined by the diffusion of metal ions into the polymer globule. If the reaction takes place in a diffusion field at a low polymer concentration, the rate of complexation is proportional to the concentration of macromolecules and the concentration of metal ions in solution.

Published: December 2022

This study was carried out to investigate antibiotic resistance pattern of Staphylococcus aureus and determine the prevalence of methicillin-resistant S. aureus (MRSA) in bovine subclinical mastitis (SCM) at dairy farms in Jos South Local Government Area, Plateau State, Nigeria. Three (3) dairy herds who met the inclusion criteria were identified and selected by convenience and using a minimum size calculation, 36 lactating cows were sampled. The cows were selected by a blind random sampling technique. Clinical examination was performed to exclude clinical mastitis (CM) and California mastitis test (CMT) to identify subclinical mastitis (SCM). A total of 142 quarter milk samples were collected for culture enrichment in nutrient broth followed by culture on mannitol salt agar (MSA) for S. aureus isolation and biochemical identification. Antimicrobial susceptibility testing (AST) of the isolates against selected antibiotics was performed by the disk diffusion method. Using R Commander version 3.6.2 data such as cow breed, age, parity, lactation, and management system were collected, and analyzed to determine their relationship with bovine subclinical mastitis. Of the total of 142 quarter milk samples collected from the 36 cows, 43 (30.3%) were positive for subclinical mastitis by CMT in 16 (44.4%) cows, and S. aureus was isolated in 29 (20.4%) of the positive samples, with MRSA from 17 (11.9%). Antibiotic susceptibility test showed resistance of S. aureus to oxacillin (60.7%), cotrimoxazole (46.4%), nalidixic acid (42.8%), ampicillin (39.2%), cefalexin (32.1%), Augmentin (14.7%), gentamicin (10.7%), ciprofloxacin (10.7%), streptomycin (10.7%) and levofloxacin (0%). The result in this study indicates the growing concern in the diary and healthcare industries of Nigeria since the strains of this pathogen is becoming more resistant to commercially available antimicrobials, and this is an alarming concern for both animal and public health. Therefore, public awareness on transmission, prevention and control of methicillin-resistant S. aureus is suggested.

Published: December 2022

An accurate calculation of premium reserves will ensure that the insurance company can pay claims. Premium reserves are funds collected by insurance companies which are the difference between the sum insured and the value of payments during the insurance period prepared for claim payments. There are several methods for calculating premium reserves, but the methods that are the focus of this study are the Zillmer method and the Premium Sufficiency method, extensions of the prospective method. This study aims to compare the two methods using the Vasicek model to determine the stochastic interest rate. Then the Ordinary Least Square method is used to estimate the Vasicek interest rate parameter. In comparing the two premium reserve methods, this study builds a simulation for reference male and female insureds using Bank Indonesia reference rate data for 2017-2021 and the Indonesian Mortality Table IV from 2019. The results of this study indicate that premiums reserve calculations using the Zillmer method yield less value than the Premium Adequacy method for both male and female insureds.
