Assortment Planning with Satisficing Customers
Authors: Pourhossein Forough , Huh Woonghee Tim , Shechter Steven M.
Published: July 2023

Limited information, time, or capacity may prevent customers from acting as utility maximizers when making purchase decisions. Rather, they would settle for a good enough option; that is, they stop searching and make a purchase as soon as they find an acceptable alternative. We incorporate this behavior in an assortment-optimization problem. Whereas different approaches to modeling customer choice are adopted in assortment planning, all assume customers are utility maximizers. Our work bridges the research streams of assortment planning and bounded rationality, particularly satisficing behavior. In addition, we define a limit for the search budget of customers, in which customers leave without purchase after examining a certain number of items. This assumption brings a new perspective to the assortment-planning literature, enabling us to capture the choice-overload effect. We prove that the firm’s problem of finding the optimal assortment is NP-hard. We further establish certain structural properties of the optimal decision, which allows us to reformulate the model as a mixed-integer program. We analytically derive a tight upper bound on the percentage loss in the firm’s expected profit for small instances when it assumes incorrectly that customers are utility maximizers. For larger instances, we take a numerical approach to determine the loss. Our results indicate that firms offering low-involvement products, among those dealing with satisficing customers, are more likely to face substantial profit loss if they ignore this behavior.

METODOLOGI PENULISAN SYEKH ‘ABD AL-HAY AL-LAKNAWI DALAM KITAB ZAFAR AL-AMANI
Authors: Soroni Mohd. Khafidz
Published: July 2023

Throughout the history of the tradition of Islamic studies, there have been various works of ‘ulum al-hadith that have been produced by hadith scholars. These works differ in their writing methodology from one work to another. To understand the differences, a study of each work and the background of the author is very necessary to be conducted to reveal and explain it. Thus, this study aims to introduce one of the figures in the discipline of ‘ulum al-hadith named Sheikh ‘Abd al-Hay al-Laknawi (d. 1304H) with a focus on one of his monumental works, namely Zafar al-Amani fi Sharh Mukhtasar al-Jurjani. This qualitative study uses content analysis methods to identify and comprehensively describe the methodology of al-Laknawi's writing in the work. From the results of the study it can be concluded that the methodology of writing al-Laknawi is seen as quite systematic and loaded with scientific discussions on issues that are quite complex in the science of hadith such as the issue of hadith hasan, the problem of doing good deeds with weak hadith, the issue of hadith mursal, issues munkar hadith and so on, along with his interpretation of the various views of the scholars presented. According to the research, this book of Zafar al-Amani is quite worthy to be placed in line with the great works of the discipline of ‘ulum al-hadith which should be studied and used as a reference by scholars and students.
Sensitivity of visible range multi-wavelength algorithms for retinal tissue oximetry to acquisition parameters
Authors: Akitegetse Cléophace , Poirier Jasmine , Sauvageau Dominic
Published: July 2023

This study examined the sensitivity of broadband spectroscopy algorithms for retinal tissue oximetry to spectral acquisition parameters. Monte Carlo simulations were conducted on a 4-layer retinal model to assess the impact of various parameters. The optimal spectral range for accurate measurements was determined to be 530 nm to 585 nm. Decreased spectral resolution below 4 nm significantly reduced accuracy. Using an acquisition area larger than the blood vessel resulted in an underestimation of oxygen saturation, especially for high values. A threshold was observed where increased light intensity had no significant impact on measurement variability. The study highlights the importance of informed parameter selection for accurately assessing retinal microcapillary oxygenation and studying local hemodynamics.
Monte Carlo samplers for efficient network inference
Authors: Kilic Zeliha , Schweiger Max , Moyer Camille , Pressé Steve
Published: July 2023

Accessing information on an underlying network driving a biological process often involves interrupting the process and collecting snapshot data. When snapshot data are stochastic, the data’s structure necessitates a probabilistic description to infer underlying reaction networks. As an example, we may imagine wanting to learn gene state networks from the type of data collected in single molecule RNA fluorescencein situhybridization (RNA-FISH). In the networks we consider, nodes represent network states, and edges represent biochemical reaction rates linking states. Simultaneously estimating the number of nodes and constituent parameters from snapshot data remains a challenging task in part on account of data uncertainty and timescale separations between kinetic parameters mediating the network. While parametric Bayesian methods learn parameters given a network structure (with known node numbers) with rigorously propagated measurement uncertainty, learning the number of nodes and parameters with potentially large timescale separations remain open questions. Here, we propose a Bayesian nonparametric framework and describe a hybrid Bayesian Markov Chain Monte Carlo (MCMC) sampler directly addressing these challenges. In particular, in our hybrid method, Hamiltonian Monte Carlo (HMC) leverages local posterior geometries in inference to explore the parameter space; Adaptive Metropolis Hastings (AMH) learns correlations between plausible parameter sets to efficiently propose probable models; and Parallel Tempering takes into account multiple models simultaneously with tempered information content to augment sampling efficiency. We apply our method to synthetic data mimicking single molecule RNA-FISH, a popular snapshot method in probing transcriptional networks to illustrate the identified challenges inherent to learning dynamical models from these snapshots and how our method addresses them.
Klebsiella pneumoniae causes bacteremia using factors that mediate tissue-specific fitness and resistance to oxidative stress

Published: July 2023

Gram-negative bacteremia is a major cause of global morbidity involving three phases of pathogenesis: initial site infection, dissemination, and survival in the blood and filtering organs. Klebsiella pneumoniae is a leading cause of bacteremia and pneumonia is often the initial infection. In the lung, K. pneumoniae relies on many factors like capsular polysaccharide and branched chain amino acid biosynthesis for virulence and fitness. However, mechanisms directly enabling bloodstream fitness are unclear. Here, we performed transposon insertion sequencing (TnSeq) in a tail-vein injection model of bacteremia and identified 58 K. pneumoniae bloodstream fitness genes. These factors are diverse and represent a variety of cellular processes. In vivo validation revealed tissue-specific mechanisms by which distinct factors support bacteremia. ArnD, involved in Lipid A modification, was required across blood filtering organs and supported resistance to soluble splenic factors. The purine biosynthesis enzyme PurD supported liver fitness in vivo and was required for replication in serum. PdxA, a member of the endogenous vitamin B6 biosynthesis pathway, optimized replication in serum and lung fitness. The stringent response regulator SspA was required for splenic fitness yet was dispensable in the liver. In a bacteremic pneumonia model that incorporates initial site infection and dissemination, splenic fitness defects were enhanced. ArnD, PurD, DsbA, SspA, and PdxA increased fitness across bacteremia phases and each demonstrated unique fitness dynamics within compartments in this model. SspA and PdxA enhanced K. pnuemoniae resistance to oxidative stress. SspA, but not PdxA, specifically resists oxidative stress produced by NADPH oxidase Nox2 in the lung, spleen, and liver, as it was a fitness factor in wild-type but not Nox2-deficient (Cybb-/-) mice. These results identify site-specific fitness factors that act during the progression of Gram-negative bacteremia. Defining K. pneumoniae fitness strategies across bacteremia phases could illuminate therapeutic targets that prevent infection and sepsis.

Pestis secunda (1356–1366 CE) is the first of a series of plague outbreaks in Europe that followed the Black Death (1346–1353 CE). Collectively this period is called the Second Pandemic. From a genomic perspective, the majority of post-Black Death strains of Yersinia pestis thus far identified in Europe display diversity accumulated over a period of centuries that form a terminal sub-branch of the Y. pestis phylogeny. It has been debated if these strains arose from local evolution of Y. pestis or if the disease was repeatedly reintroduced from an external source. Plague lineages descended from the pestis secunda, however, are thought to have persisted in non-human reservoirs outside Europe, where they eventually gave rise to the Third Pandemic (19th and 20th centuries). Resolution of competing hypotheses on the origins of the many post-Black Death outbreaks has been hindered in part by the low representation of Y. pestis genomes in archaeological specimens, especially for the pestis secunda. Here we report on five individuals from Germany that were infected with lineages of plague associated with the pestis secunda. For the two genomes of high coverage, one groups within the known diversity of genotypes associated with the pestis secunda, while the second carries an ancestral genotype that places it earlier. Through consideration of historical sources that explore first documentation of the pandemic in today’s Central Germany, we argue that these data provide robust evidence to support a post-Black Death evolution of the pathogen within Europe rather than a re-introduction from outside. Additionally, we demonstrate retrievability of Y. pestis DNA in post-cranial remains and highlight the importance of hypothesis-free pathogen screening approaches in evaluations of archaeological samples.

Assessment of toxicity of industrial wastes using crop plant assays
Authors: Teacă Carmen Alice , Bodîrlău Ruxanda
Published: July 2023

Environmental pollution has a harmful action on bioresources, including agricultural crops. It is generated through many industrial activities such as mining, coal burning, chemical technology, cement production, pulp and paper industry, etc. The toxicity of different industrial wastes and heavy metals excess was evaluated using crop plant assays (germination and hydroponics seedlings growth tests). Experimental data regarding the germination process of wheat (from two cultivars) and rye seeds in the presence of industrial wastes (thermal power station ash, effluents from a pre-bleaching stage performed on a Kraft cellulose – chlorinated lignin products or chlorolignin), along with use of an excess of some heavy metals (Zn and Cu) are presented here. Relative seed germination, relative root elongation, and germination index (a factor of relative seed germination and relative root elongation) were determined. Relative root elongation and germination index were more sensitive indicators of toxicity than seed germination. The toxic effects were also evaluated in hydroponics experiments, the sensitivity of three crop plant species, namely Triticum aestivum L. (wheat), Secale cereale (rye), and Zea mays (corn) being compared. Physiological aspects, evidenced both by visual observation and biometric measurements (mean root, aerial part and plant length), as well as the cellulose and lignin content were examined.
Analysis of switchgrass characteristics using near infrared spectroscopy
Authors: Labbé Nicole , Ye Xiaofei P. , Franklin Jennifer A. , Womac Alvin R. , Tyler Donald D. , Rials Timothy G.
Published: July 2023

Switchgrass varieties grown under various environments were investigated by dispersive and Fourier Transform Near-Infrared (NIR) spectrometers. The collected NIR spectra were analyzed using multivariate approaches. More specifically, principal component analysis (PCA) and projection to latent structures (PLS) regression techniques were employed to classify and predict characteristics of the switchgrass samples. The multivariate results were compared to reflectance indices that are commonly used to study the physiological performance of plants. From near infrared spectra, discrimination between the two growth locations was successfully achieved by PCA. Separation based on the ecotype and the rate of fertilizer applied to the field was also possible by the multivariable analysis of the spectral data. For the classification/ discrimination of the switchgrass samples, the near infrared spectra collected by the dispersive and the Fourier Transform spectrometers provided similar results. From the two near infrared data sets robust models were developed to predict non-structural carbohydrates content and the rate of nitrogen applied to the field. However, the spectra collected by the dispersive spectrometer resulted in more accurate models for these samples.

STABILITY ANALYSIS OF RIVLIN-ERICKSEN FLUID FILM WITH HEAT TRANSFER THROUGH AN ANNULAR POROUS MEDIUM
Authors: Awasthi Mukesh Kumar , Shukla Atul Kumar , Agarwal Shivam , Singh Abhishek Kumar , Shukla Pankaj
Published: July 2023

A theoretical study was conducted to analyze the stability of the interface between viscous and viscoelastic fluids,
considering heat and mass transfer between the phases. The study used Rivlin-Ericksen's model for viscoelastic
liquid and an irrotational flow theory to analyze the problem. A rigid cylinder surrounded the annular region of the viscoelastic liquid and viscous fluid. The viscous fluid was located in the inner region, while the viscoelastic liquid was in the outer region. The analysis did not take into account tangential stress, considered viscosity through normal stress balance, and did not impose no-slip conditions at the two cylindrical rigid boundaries. The results indicate that the interface stability is enhanced under porous conditions due to the heat/mass transfer. A medium with higher permeability stabilizes the interface, while a medium with higher porosity negatively affects the viscoelastic interface. The study compared the stabilizing characteristics of the Rivlin-Ericksen fluid interface under a nonporous and porous medium and found that the interface is more stable under porous media.

Basic principles of criminal procedure in the Second Polish Republic
Authors: Baltyzar Dawid Patryk , Łukasik Ilona Maria
Published: July 2023

After Poland gained independence, it was necessary to unify many areas of law. There were three legislations in force in the area of criminal procedure at that time, i.e. the Russian Criminal Procedure Act of 1864, the Austrian Criminal Procedure Code of 1873, and the German Criminal Procedure Code of 1874. The Codification Commission, which was established in 1919, was responsible for the creation of the Polish codification. Its work resulted in the Code of Criminal Procedure issued in the form of a regulation, which came into force on 1 July 1929. The Code represented a mixed form of trial, with liberal tendencies manifesting themselves in it. It was based on the principles set out not only in the general provisions but also in the further parts. The principles of the criminal proceedings did not remain in a hierarchical relationship with each other. Conciseness, synthesis and a high level of legislative technique are the characteristic features of this very innovative codification.

Authors: Mariño Luis-Fernando , Hernández Rosa-Virginia , Hernández-Suárez César-Augusto
Published: July 2023

The purpose of the work was to characterize problem solving as a way of thinking manifested by a group of students who are trained to be math teachers. The research with a qualitative approach and a design from the grounded theory was focused on answering the question, how are the ways of understanding and ways of thinking of a group of mathematics teachers in training when they solve problems in discrete domains? The participants were 21 students who took a course in Number Theory in a program that trains professors of Mathematics at the Francisco de Paula Santander University (Cúcuta, Colombia). For the analysis of data from nine teaching experiments and a semi-structured retrospective interview, open, axial and selective coding processes were used. Among the findings is the way the participants interpreted necessary conditions, sufficient conditions, relationships, convergents and the infinite solutions to each problem. These ways of interpreting led students to understand relationships, patterns, and strategies for convincing and solving problems in local contexts. At the core of the theory, ways of understanding and thinking were characterized as a variational process ranging from interpretation as a way of understanding problem solving in local contexts to establishing relationships, creating strategies for generalization, and testing as ways of thinking about problem solving in a variety of contexts.

Pregnant women with preeclampsia are advised to opt for a cesarean section. Cesarean section is a method of labor that in which the fetus is delivered through a place in front of the abdomen and uterine wall, provided that it is intact and the weight of the fetus is above 500 grams. This study aimed to find out how women with preeclampsia could manage pain and the effect of oxytocin massages. This paper is a case study on a 31-year-old female patient diagnosed with preeclampsia at Muhammadiyah Hospital Lamongan. After performing the Benson relaxation technique (in which the patient took deep breaths by silently saying the selected words (dhikr) for 10-15 minutes) showed that the pain in the abdomen was reduced to a scale of level 3 pain. After performing oxytocin massages the patient said the base started to come out and she can position the baby correctly while breastfeeding. Implementation of the relaxation technique and the oxytocin massage was in accordance with the existing data on the planning, namely pain management and oxytocin massage. The results of the evaluation showed that there was a decrease in pain and breast milk came out.

Published: July 2023

School-age children felt anxious due to changes and new habits that were cultivated during the COVID-19 pandemic. They need family support to suppress and minimize anxiety. This study aimed to determine the relationship between family support and anxiety levels in school-age children during the pandemic. This was a cross-sectional study with a sample of 83 people (each a family member or a school-age child) determined by the Simple Random Sampling technique following inclusion criteria. The data were analyzed using the Spearman Rank correlation technique. The results showed that the majority of family support was high at 75 people (90.4%), the anxiety level of school-age children was mild at 76 people (91.6%), and there was a significant relationship between family support and anxiety levels of school-age children evidenced by the p-value of 0.003 < 0.05 with the strength of the relationship ”quite strong” (correlation coefficient - 0.325) and the direction of the relationship ”negative.” Family support is one of the factors that can affect the level of anxiety in individuals in the family, including school-age children. School-aged children who get family support, in the form of informational, emotional, instrumental, and assessment support, will feel that they are cared for and loved which results in their self-confidence and self-esteem increasing. Individuals who feel this way will feel confident that they can master and overcome their problems.

Published: July 2023

Ageing is often associated with sleep disorders. This study aimed to describe the effect of using an Android application on family support in the sleep patterns of the elderly. The study used a cross-sectional survey design conducted among the elderly to assess the use of android-based applications in identifying the sleep pattern experienced and the perceived-family support. The research sample was 98 people selected by convenience sampling and snowball sampling techniques. Researchers enhanced family support through an Android app. The mean value of sleep patterns before using the app was 4.25 and after using the app was 8.35. The correlation test showed that perceived-family support had a significantly strong correlation with sleep patterns with a positive correlation (correlation coefficient 0.779, p-value 0.001; Table 5). The higher the family support perceived by the elderly, the better their sleep pattern. The study concluded that the elderly at risk of dementia often experience disturbed sleep patterns. Families play an important role in helping the improvement of elderly sleep patterns. Android applications can be a technological innovation in increasing family support for the elderly.

Published: July 2023

In this modern era, child marriage still remains a practice in some regions. This phenomenon damages the normal life of families and negatively affects the human capitals of Indonesia. Higher number of child marriages would lead to increase in the divorce rates than normal, as those involved in this marriage have not developed the necessary emotional control for solving problems that might arise during these marriages. This led many to the path of divorce. The goal of this research is to understand the factors that led to child marriage in Cintapuri Village, Banjar Regency, Banjarmasin. This research uses the qualitative descriptive method with phenomenological model. Subjects in this research were teenage girls married in the age of 14-16 with Junior High School (SMP) being their last education level, parents, and village governance apparatus in Cintapuri Village, Banjar Regency, Banjarmasin. The data from this research was collected through careful observations and interviews with people related to the research’s objective. The result of this research shows there are several factors leading to the rampant cases of child marriage, such as economical, educational, and cultural factors. Looked through from an economical point-of-view, many parents are marrying their children off to alleviate their economic burden. From an educational point-of-view, many parents are not aware of the adverse effects of child marriage and the laws that regulate the minimum age of marriage, because of the lack of education. From a cultural point-of-view, parents are feeling nervous and ashamed for the fact that their daughter do not have a partner yet, leading them in search of a suitable partner for their daughter even though their daughter do not always approve of the parent’s suitable partner.

Objective: In this study, the effect of interspecific and intraspecific hybridization on seed germination of pitaya was investigated.
Material and Methods: Self-infertile 'Bloody Mary' (Hylocereus polyrhizus) was used as the maternal parent and 'Cosmic Charlie' (Hylocereus undatus), 'Red Jaina' (Hylocereus polyrhizus) and 'White Jaina' (Hylocereus undatus) were used as pollinators in this study. Flowers were pollinated at three different times (10: 00 pm, 00: 00 am, and 06.00 am). After pollination, seeds from each pollination combination were sown. The germination rate, average germination time, germination energy and germination index of the sown seeds were determined depending on pollination time and pollinator cultivars.
Results: The research findings indicated that the germination rate was 100% in all seed sowing combinations, depending on different pollinator cultivars ('Cosmic Charlie' and 'White Jaina' are in different species from the maternal parent) and pollination times. The results revealed that interspecific hybridization did not have a negative effect on seed germination. On the other hand, germination time, germination energy and index differed as per pollinator type and pollination hours.
Conclusion: According to the findings, it was concluded that interspecific hybridization in pitaya does not have problem in seed germination and results might offer an infrastructure for future breeding programme in pitaya.

Host-produced antimicrobial peptides (AMPs) are critical for the integrity of the gut epithelial barrier as they prevent the pathogenesis of the enteric microbiota. Here, we report that intestinal antimicrobial activity is reduced, and epithelial permeability is increased in a morphine-dependent mouse model. Antimicrobial activity and permeability are restored by fecal transplant (FMT) from morphine-naïve mice or by oral gavage of sodium butyrate. Butyrate levels are reduced in the fecal samples of morphine-treated mice concomitant with a reduction in the phylum, Firmicutes. The alpha diversity of the microbiome is also restored by oral butyrate in morphine-dependent mice. FMT or sodium butyrate prevents downregulation of the antimicrobial peptide, Regenerating islet-derived 3 gamma (Reg3γ), and the development of antinociceptive tolerance in morphine-dependent mice. These data implicate impairment of the antimicrobial activity of the intestinal epithelium as a mechanism by which morphine disrupts the microbiota-gut-brain axis.

While the majority of individuals with coronavirus disease 2019 (COVID-19) recovercompletely, a significant percentage experience persistent symptoms, which has beencharacterized as Long COVID and may be associated with cardiac and autonomicdysfunction. We evaluated heart rate variability (HRV) at rest and during deep-breathing(M-RSA) in patients with Long COVID. Case-control design involved 21 patients with LongCOVID and 20 controls; the HRV was evaluated (Polar® system) at rest in the supineposition and during M-RSA and expressed in time domain and non-linear analysis. We foundthat Long COVID in patients resulted in a reduction HRV measures compared to controls:Supine [Mean_iRR=716.9±948.2 vs 948.2±99.6 p<0.001; STD_iRR=12.7±6.9 vs 45.6±20.7p<0.001; STD_HR=1.7±0.7 vs 3.1±1.2 p<0.001; SD1=6.9±4.1 vs 29.5±14.4 p<0.001;SD2=16.4±9.0 vs 56.7±25.6 p<0.001; alpha2=0.5±0.2 vs 0.7±0.1 p<0.001)]; M-RSA:[Mean_iRR=685.9±97.4 vs 845.3±112.4 p<0.001; STD_iRR=24.8±14.9 vs 95.7±111.8p<0.001; Mean_HR=89.4±12.9 vs 72.8±10.3 p<0.001; STD_HR=3.2±1.3 vs 6.0±2.1p<0.001; rMSSD=14.7±8.7 vs 45.2±19.9 p<0.001; RR_tri-index=6.2±3.4 vs 15.1±3.3p<0.001)]. In conclusion, Long COVID negatively impacted HRV at rest and duringdeep-breathing. These findings may imply impairment of cardiac autonomic control whensymptoms of COVID-19 persist following initial recovery.

Background
European Epidemic Intelligence (EI) systems receive vast amounts of information and data on disease outbreaks and potential health threats. The quantity and variety of available data sources for EI, as well as the available methods to manage and analyze these data sources are constantly increasing. Our aim was which innovations, according to EI practitioners, could improve the detection, monitoring and analysis of disease outbreaks and emergence of new pathogens.
Methods
We conducted a qualitative study to identify the needs for innovation expressed by 33 EI practitioners of national public health and animal health agencies in five European countries and at the European Center for Disease Control (ECDC). We adopted a step-wise approach to identify the EI stakeholders, to understand the problems they faced concerning their EI activities, to validate and further define practitioners’ problems to offer solutions. We characterized their EI activities, their professional logics, and the desired changes in their activities.
Results
Our analysis highlights that EI practitioners wished to collectively review their EI strategy in order to enhance their preparedness for emerging infectious diseases, adapt their routine to manage an increasing amount of data and to have methodological support for cross-sectoral analysis. Practitioners were in demand of timely, validated and standardized data acquisition processes by text mining of various sources; better validated dataflows respecting the data protection rules; and more interoperable data with homogeneous quality levels and standardized covariates sets for epidemiological assessments of national EI. The set of solutions, identified to facilitate risk detection and risk assessment, included visualization, text-mining, predefined analytical tools combined with methodological guidance. Practitioners also highlighted their preference for a partial rather than a full automation of analyses in order to keep control over the data, inputs and adapt parameters to versatile objectives and characteristics.
Conclusions
Overall, the set of solutions had to be based on holistic and integrated approaches for monitoring zoonosis and antimicrobial resistance and on a harmonization between agencies and sectors, while keeping flexibility in the choice of tools and methods. The technical requirements should be defined in detail by iterative exchanges with EI practitioners and decision-makers.
