description: Ductile fracture through void growth and coalescence depends significantly on the plastic anisotropy of the material and on void size, as shown by experiments and/or numerical simulations through several studies. Macroscopic (homogenized) yield criteria aiming at modeling nanoporous materials have been proposed only for the growth regime, i.e. non-interacting voids. The aim of this study is thus to provide a yield criterion for nanoporous materials relevant for the coalescence regime, i.e. when plastic flow is localized between voids. Through homogenization and limit analysis, and accounting for interface stresses at the void-matrix interface, analytical coalescence criterion is derived under the following conditions: axisymmetric loading, orthotropic material obeying Hill's plasticity, cylindrical voids in cylindrical unit-cell. Incidentally, an orthotropic extension of the existing isotropic modeling of interface stresses through limit analysis is described and used. The proposed coalescence criterion is then extended to account for combined tension and shear loading conditions. Numerical limit analyses have been performed under specific conditions / materials parameters to get supposedly exact (up to numerical errors) results of coalescence stress. A good agreement between the analytical coalescence criteria derived in this study and numerical results is found for elongated spheroidal voids, making them usable to predict the onset of void coalescence in ductile fracture modeling of nanoporous materials.

description: For revealing molecular markers related to the traits of multiple lumbar vertebrae in sheep, we analyze the relationship between NR6A1 gene polymorphism and lumbar vertebrae number traits in Xinjiang Kazakh sheep. Lumbar muscle tissues were collected from 6-lumbar spine (L6) Kazak sheep and 7-lumbar spine (L7) Kazak sheep and the intron-8 of NR6A1 gene was amplified by PCR. The SNP locus was detected by the PCR-SSCP method. One-Way ANOVA and an Independent Chi-square Test is adopted to analyze the genotype association with lumbar spine number variation. There were two SNP loci in the intron-8 of the NR6A1 gene: IVS8-188 and IVS8-281. One-Way ANOVA and Independent Chi-square Test indicated a significant association between IVS8-281 and lumbar spine number. The SNP locus of NR6A1 gene intron 8 (IVS8-281G > A) could play a certain role in the variation of lumbar spine number in Xinjiang Kazakh sheep and demonstrates potential to accelerate the sheep breeding of selection process.
Surgical correction of jejunal obstruction by ductus deferens (gut tie).
Creators: name: Weaver, A. David
Publisher: name: The Bovine Practitioner
Year: 1987

description: In a review of 129 cases of pelvic hernia due to this cause encountered over a period of 30 years, the majority were right-sided and were corrected by rectal manipulation and rupture of the occluding band. Laparotomy, however has been performed since 1813 and has been claimed to be the preferable method, in particular during the later years of the nineteenth century. The condition of “gut tie” is described in detail including left flank laparotomy for section of the intra-abdominal strangulating cord by a bistoury. This form of incarceration appears to be much less common today. In 100 cattle with intestinal obstruction Pearson found that the etiology involved inflammatory lesions caused by traction castration or traumatic lesions of the parietal peritoneum in only four cattle. Adhesions were not present in this current case. Similar obstructions of jejunoileal segments have been caused by a persistent hepatic round ligament, para-ovarian bands and vitello-umbilical bands or by adventitious fibroserosal cords. Differential diagnosis from such abdominal bands was impossible in this case but in retrospect might have been suspected since this particular band is more caudal than other forms reported in the past twenty years. It is doubtful whether it could have been ruptured by digital manipulation per rectum and such manipulation would also have been unnecessarily hazardous to the steer.

description: Nella società odierna, padroneggiare la lingua è un aspetto trasversale molto importante, in quanto permette di relazionarsi e comunicare in diversi contesti e situazioni. Il Piano di studi della scuola dell’obbligo ticinese (DECS, 2015) sottolinea come sia necessario, per sviluppare una buona competenza linguistica, ampliare il proprio bagaglio lessicale, che consente ad ogni persona di variare l’uso di parole e termini in modo appropriato alle circostanze. Non solo: avere a disposizione una pluralità di vocaboli permette di perfezionare la capacità di strutturare e verbalizzare un pensiero complesso. Lo scopo di questa ricerca è stato quello di capire se una classe di terza elementare potesse essere sensibilizzata nella scelta e nell’utilizzo delle parole. Gli allievi hanno svolto un percorso “immersivo” nel mondo delle parole, analizzando come queste giochino un ruolo fondamentale in un testo. Si è voluto dunque rendere attenti i bambini al ruolo fondamentale delle parole, facendo capire come la loro scelta ed il loro utilizzo sia “un’arma pericolosa”, qualora venissero utilizzate in maniera imprecisa. L’indagine ha fatto emergere come i bambini siano curiosi e “insaziabili” anche nell’arricchimento lessicale: ciò ha permesso di far crescere in loro un atteggiamento di criticità verso lemmi poco adeguati e generici, e di abbandonare una certa “pigrizia” iniziale nell’utilizzo di parole scontate.

Surgical management of umbilical masses in calves
Creators: name: Trent, A. M.
Publisher: name: The Bovine Practitioner
Year: 1987

description: Umbilical masses in calves are commonly encountered by bovine practitioners. They may vary in size from a small, discrete swelling to an extremely large mass. A mass at the umbilicus represents one of two basic situations: herniation or inflammation. A simple hernia is characterized by its reducibility, lack of pain on palpation, and the presence of a hernial ring. Inflammation (or infection) may be localized to the umbilical opening alone, or extend to involve intra-abdominal umbilical cord remnants. Both hernial and inflammatory components can be present in a single umbilical mass. In these cases the mass may be partially reducible, but will also have a component which is non-reducible. Unlike pigs, calves rarely incarcerate their hernias unless a significant inflammatory component is already present; therefore, any mass which is not completely reducible should be considered to have an inflammatory component.

Probing Split-Ring Resonator Permeabilities with Loop-Gap Resonators

description: A method is proposed to experimentally determine the effective complex permeability of split-ring resonator (SRR) arrays used in the design of metamaterials at microwave frequencies. We analyze the microwave response of a loop-gap resonator (LGR) whose bore has been partially loaded with one or more SRRs. Our analysis reveals that the resonance frequency, magnetic plasma frequency, and damping constant of the effective permeability of the SRR array can be extracted from fits to the reflection coefficient (S11) of an inductively-coupled LGR. We propose LGR designs that would allow both a one-dimensional array of SRRs and small three-dimensional arrays of SRRs to be characterized. Finally, we demonstrate the method using a toroidal LGR loaded with a single extended SRR of length z.

Brazilian Portuguese null objects and Spanish differential object marking
Creators: name: Cyrino, Sonia
Publisher: name: Zenodo
Year: 2021

description: Animacy features have been known to trigger syntactic phenomena. In this paper,
 I focus on differential object marking (DOM), and the null object in Brazilian
 Portuguese, where such features are relevant. I assume that animacy corresponds to
 a specification of Person features, and lack of animacy implies that no Person
 features are encoded in a DP. Furthermore, I propose that animacy is encoded in a
 dedicated functional head. Animate DPs (i.e. DOM in Spanish and animate objects
 in BP) move to Spec, FPanimacy , a projection above V, below v, to check a person
 feature. Crucially, inanimate DPs stay in situ. They are not DOM marked in Spanish
 and, by virtue of being low, they can be licensed as DP ellipsis in BP. This
 analysis may contribute to work seeking to grasp the role of referential hierarchies in
 syntax.

description: The feasibility is demonstrated of a new approach to the vapor phase lubrication of ceramics using organophosphorus compounds. The surface of SiC is shown to be unreactive for the decomposition of trimethylphosphite, (CH3O)3P, a simple model for organophosphorus vapor phase lubricants such as tricresylphosphate. In order to activate the surface of SiC it has been exposed to Fe(CO)5 at a temperature of 600 K. Chemical vapor deposition serves as a means of depositing Fe on the SiC surface. The Fe-modified SiC surface is then shown to induce the decomposition of adsorbed (CH3O)3P. The mechanism of (CH3O)3P decomposition is similar to that observed on Fe(110) surfaces modified by the presence of oxygen. It is initiated by P–O bond cleavage to produce adsorbed methoxy groups, CH3O(ad), which then decompose by β-hydride elimination resulting in H2, CO, H2CO, and CH3OH desorption. It is suggested that chemical vapor deposition of metals using high vapor pressure metal-containing compounds such as Fe(CO)5 can serve as a mechanism for continuous, in situ activation of ceramic surfaces for vapor phase lubrication in high temperature engines.

description: Oggigiorno l’informatica è sempre più presente nella nostra vita e, con la creazione di supporti innovativi, gioca un ruolo importante anche nell’ambito dei DSA. Con il presente lavoro di ricerca si vogliono esporre le opinioni di alcuni docenti riguardo l’utilizzo delle nuove tecnologie da parte di allievi con dislessia. Per fare ciò sono stati scelti tre docenti titolari, con i rispettivi docenti di sostegno pedagogico, che nelle loro classi hanno ciascuno un allievo con dislessia. In particolare gli interrogativi miravano ad indagare le modalità di utilizzo dei supporti informatici e i loro effetti sull’apprendimento (a scuola e a casa) e sullo sviluppo personale del bambino. Dalle interviste emerge che in tutti e tre i casi viene proposto l’utilizzo del computer, anche se attraverso modalità differenti. In generale i docenti titolari sostengono che gli ausili informatici permettano di migliorare il rendimento scolastico dell’allievo e la sua motivazione ad apprendere e che abbiano un’influenza positiva sull’autonomia e sull’autostima del bambino con dislessia. Anche i docenti di sostegno credono vi possa essere una relazione positiva tra le variabili, a patto però che si agisca anche sul contesto. Dai dati raccolti risulta dunque evidente l’importanza di una collaborazione con le famiglie e il fatto che gli ausili informatici possano certo essere un aiuto, ma non costituiscono la soluzione al problema. Inoltre i loro effetti possono presentare grande variabilità. Relatrici: Feliciana Fiscalini-Tocchetto e Sara Giulivi

description: We re-examine the question of radiative symmetry breaking in the standard model in the presence of right-chiral neutrinos and a minimally enlarged scalar sector. We demonstrate that, with these extra ingredients, the hypothesis of classically unbroken conformal symmetry, besides naturally introducing and stabilizing a hierarchy, is compatible with all available data; in particular, there exists a set of parameters for which the model may remain viable even up to the Planck scale. The decay modes of the extra scalar field provide a unique signature of this model which can be tested at LHC.

Surgical fistula as an aid in the treatment of chronic bloat in cattle.

name: Frederiksen, E. D.
Publisher: name: The Bovine Practitioner
Year: 1987

description: Medical treatment of chronic bloat in cattle often fails, resulting in acute death, no weight gain, or poor weight gain. Several devices have been developed to facilitate the treatment of chronic bloat. These consist of self-retaining trocars, plastic or metal fistulas, and pop-off valves. Usually these devices become plugged postoperatively, either by local infection of the rumen or by ingesta. If an animal has been treated medically for bloat on three occasions within a short period of time, the case may be classified as chronic. Surgical intervention is then recommended. Young beef animals that develop chronic bloat soon after they are started on high-concentrate feed are the usual candidates for this procedure.

Speech Dereverberation Using Nonnegative Convolutive Transfer Function and Spectro temporal Modeling

Subjects: subject: Sound (cs.SD)

description: This paper presents two single channel speech dereverberation methods to enhance the quality of speech signals that have been recorded in an enclosed space. For both methods, the room acoustics are modeled using a nonnegative approximation of the convolutive transfer function (NCTF), and to additionally exploit the spectral properties of the speech signal, such as the low rank nature of the speech spectrogram, the speech spectrogram is modeled using nonnegative matrix factorization (NMF). Two methods are described to combine the NCTF and NMF models. In the first method, referred to as the integrated method, a cost function is constructed by directly integrating the speech NMF model into the NCTF model, while in the second method, referred to as the weighted method, the NCTF and NMF based cost functions are weighted and summed. Efficient update rules are derived to solve both optimization problems. In addition, an extension of the integrated method is presented, which exploits the temporal dependencies of the speech signal. Several experiments are performed on reverberant speech signals with and without background noise, where the integrated method yields a considerably higher speech quality than the baseline NCTF method and a state of the art spectral enhancement method. Moreover, the experimental results indicate that the weighted method can even lead to a better performance in terms of instrumental quality measures, but that the optimal weighting parameter depends on the room acoustics and the utilized NMF model. Modeling the temporal dependencies in the integrated method was found to be useful only for highly reverberant conditions.
Rethinking Implicit Agents: Syntax cares but not always
Creators: name: Michelioudakis, Dimitris
Publisher: name: Zenodo
Year: 2021

description: In this paper, I examine implicit control in Greek passives, both verbal passives and
 a passive-like construction in the nominal domain, namely complex event
 nominals with an agentive interpretation but a genitive theme DP as the only
 argument which is realised overtly. The availability of implicit control into temporal
 gerundival clauses depends on the features of the internal argument and the
 varying interpretation of the implicit argument. I argue that the implicit agent is only
 represented syntactically as a covert arbitrary pronoun and is thus able to exert
 implicit control as long as that pronoun does not trigger relativised minimality
 effects, blocking promotion of/Agree with the internal argument. The very
 existence of relativised minimality effects is a purely syntactic argument in favour of
 the syntactic reality of implicit arguments.

description: Conventional beam orientation optimization (BOO) algorithms for IMRT assume that the same set of beam angles is used for all treatment fractions. In this paper we present a BOO formulation based on group sparsity that simultaneously optimizes non-coplanar beam angles for all fractions, yielding a fraction-variant (FV) treatment plan. Beam angles are selected by solving a multi-fraction FMO problem involving 500-700 candidate beams per fraction, with an additional group sparsity term that encourages most candidate beams to be inactive. The optimization problem is solved using the Fast Iterative Shrinkage-Thresholding Algorithm. Our FV BOO algorithm is used to create non-coplanar, five-fraction treatment plans for prostate and lung cases, as well as a non-coplanar 30-fraction plan for a head and neck case. A homogeneous PTV dose coverage is maintained in all fractions. The treatment plans are compared with fraction-invariant plans that use a fixed set of beam angles for all fractions. The FV plans reduced mean and max OAR dose on average by 3.3% and 3.7% of the prescription dose, respectively. Notably, mean OAR dose was reduced by 14.3% of prescription dose (rectum), 11.6% (penile bulb), 10.7% (seminal vesicle), 5.5% (right femur), 3.5% (bladder), 4.0% (normal left lung), 15.5% (cochleas), and 5.2% (chiasm). Max OAR dose was reduced by 14.9% of prescription dose (right femur), 8.2% (penile bulb), 12.7% (prox. bronchus), 4.1% (normal left lung), 15.2% (cochleas), 10.1% (orbits), 9.1% (chiasm), 8.7% (brainstem), and 7.1% (parotids). Meanwhile, PTV homogeneity defined as D95/D5 improved from .95 to .98 (prostate case) and from .94 to .97 (lung case), and remained constant for the head and neck case. Moreover, the FV plans are dosimetrically similar to conventional plans that use twice as many beams per fraction. Thus, FV BOO offers the potential to reduce delivery time for non-coplanar IMRT.
INDUSTRIAL ENGINEERING AS AN ACADEMIC STUDY AND APPLICATION OF COMPLEX PROCESSES

description: Industrial engineering is a multidisciplinary discipline that aims to optimize complicated processes in many sectors. The process entails doing research across several disciplines, such as mathematics, statistics, engineering, and economics, with the aim of enhancing efficiency, productivity, and quality. Industrial engineers optimize processes, minimize inefficiencies, and enhance overall performance via the use of problem-solving and analytical abilities. The implementation of industrial engineering concepts has a significant influence on manufacturing, healthcare, transportation, and service sectors. Industrial engineers use cutting-edge technology and inventive strategies to provide sustainable and economically efficient solutions. With the rising need for efficiency and optimization in today's competitive market, the significance of industrial engineering is growing. Industrial engineers use their theoretical knowledge and apply it practically to determine the future of several industries. Industrial engineering encompasses not only the efficient implementation of processes, but also the enhancement of safety protocols, the mitigation of environmental effects, and the promotion of higher employee contentment. Industrial engineers use concepts of ergonomics and human factors engineering to guarantee that working settings are built in a manner that minimizes physical strain and cognitive overload. This guarantees enhanced employee contentment and reduced likelihood of harm.

description: Abstract: "An approach for the accurate solution of optimal control problems that arise in batch distillation is developed and demonstrated. Since the optimal control problem has a natural partitioning of control variables and state variables, we develop a nonlinear programming decomposition strategy to (1) exploit the block matrix form of the discretized differential equations that results from using collocation on finite elements, and (2) perform the optimization in the reduced space of the control variables. State variables for each finite element are determined by linearized differential equations and information is passed from element to element by chainruling the state information. In addition, the nonlinear programming strategy has a great deal of flexibility to determine control variable discontinuities and enforce a wide variety of state and control variable constraints. In this study, we also consider characteristics of the maximum batch distillate problem and show that our approach is especially useful for the optimization of detailed tray-by-tray models with tray and condenser holdups. Here we discuss two formulations: an inequality path constrained problem and the classical endpoint constrained problem. In both cases interesting and unusual optimal policies are determined and compared to current practice. Moreover, parallels are observed between optimal reflux policies for these two problems, and these are also related to findings from previous studies. To handle these problems, nonlinear programs of up to 8000 variables are solved reasonably quickly on a small workstation. Finally, it is observed that more complex batch distillation problems can be handled in a straightforward manner through this approach."

description: The scattering amplitudes of gauge bosons in heterotic and open superstring theories are related by the single-valued projection which yields heterotic amplitudes by selecting a subset of multiple zeta value coefficients in the $α'$ (string tension parameter) expansion of open string amplitudes. In the present work, we argue that this relation holds also at the level of low-energy expansions (or individual Feynman diagrams) of the respective effective actions, by investigating the beta functions of two-dimensional sigma models describing world-sheets of open and heterotic strings. We analyze the sigma model Feynman diagrams generating identical effective action terms in both theories and show that the heterotic coefficients are given by the single-valued projection of the open ones. The single-valued projection appears as a result of summing over all radial orderings of heterotic vertices on the complex plane representing string world-sheet.

description: Each year over three hundred bulls enter the Saskatoon Feed testing station and each year about forty percent of the group meet the standards set for food conversion, back fat thickness and testicular circumference. Of these successful bulls up to twenty five percent are rejected by “evaluators” on the basis of unsound conformation. In October of 1985 we were asked to evaluate the ‘’feet and legs” of bulls undergoing feeding trials. Our assignment, therefore, was to define, in objective terms the reasons for the culling. Because it had been suggested that poor limb and hoof conformation was likely to be an important consideration our initial efforts were directed towards developing a system for measuring the conformation of the bulls under trial.

description: Deriving a good model for multitalker babble noise can facilitate different speech processing algorithms, e.g. noise reduction, to reduce the so-called cocktail party difficulty. In the available systems, the fact that the babble waveform is generated as a sum of N different speech waveforms is not exploited explicitly. In this paper, first we develop a gamma hidden Markov model for power spectra of the speech signal, and then formulate it as a sparse nonnegative matrix factorization (NMF). Second, the sparse NMF is extended by relaxing the sparsity constraint, and a novel model for babble noise (gamma nonnegative HMM) is proposed in which the babble basis matrix is the same as the speech basis matrix, and only the activation factors (weights) of the basis vectors are different for the two signals over time. Finally, a noise reduction algorithm is proposed using the derived speech and babble models. All of the stationary model parameters are estimated using the expectation-maximization (EM) algorithm, whereas the time-varying parameters, i.e. the gain parameters of speech and babble signals, are estimated using a recursive EM algorithm. The objective and subjective listening evaluations show that the proposed babble model and the final noise reduction algorithm significantly outperform the conventional methods.

description: We present time-resolved measurements of electron transport through a quantum dot. The measurements were performed using a nearby quantum point contact as a charge detector. The rates for tunneling through the two barriers connecting the dot to source and drain contacts could be determined individually. In the high bias regime, the method was used to probe excited states of the dot. Furthermore, we have detected bunching of electrons, leading to super-Poissonian noise. We have used the framework of the full counting statistics (FCS) to model the experimental data. The existence of super-Poissonian noise suggests a long relaxation time for the involved excited state, which could be related to the spin relaxation time.

description: Background: The fixed-dose combination foam formulation of calcipotriene 0.005% plus betamethasone dipropionate 0.064% (Cal/BD) has demonstrated efficacy and a favorable safety profile for the treatment of plaque psoriasis. Recently, a topical lotion of the combination of halobetasol 0.01% plus tazarotene 0.045% (HP/TAZ) was approved for treating adult plaque psoriasis. Currently, no head-to-head studies have compared Cal/BD foam with HP/TAZ lotion. Objective: Compare the effectiveness and drug incremental cost per responder (ICPR) of Cal/BD foam vs. HP/TAZ lotion in moderate-to-severe plaque psoriasis. Methods: An anchor-based, matching-adjusted indirect comparison was conducted for PGA treatment success (Physician’s Global Assessment of “clear” or “almost clear,” [PGA 0/1] with at least a 2-point improvement) using individual patient data from 3 randomized clinical studies of Cal/BD foam and published data from 2 randomized, Phase 3 clinical studies of HP/TAZ lotion. The number needed to treat and ICPR were also calculated. Results: After reweighting of patients in the Cal/BD foam studies to match summary baseline characteristics of the HP/TAZ lotion study patients and anchoring to vehicle effect, 4 weeks of Cal/BD foam produced a significantly greater rate of treatment success than 8 weeks of HP/TAZ lotion treatment (51.4 vs. 30.7%; treatment difference = 20.7%, p Conclusions: The indirect comparison analyses showed that Cal/BD foam was associated with a greater rate of treatment success, lower ICPR, and quicker treatment response than HP/TAZ lotion in adult patients with moderate-to-severe plaque psoriasis.
Prophylaxis: breeding, feeding, housing and hoof trimming

description: Prevention of ruminant digital disease is the modern approach to this increasingly recognized economically significant problem. Successful cattle breeders and feeders are no longer satisfied with successful treatment of a lame animal. They demand to know why the animal became lame and how to prevent further lamenesses in their herds. They are aware that when an animal becomes lame a financial loss has already occurred and treatment only limits the amount of loss. Only a small profit is realized per healthy animal under ideal conditions and a herd lameness problem very quickly leads to economic disaster. When treating a lame animal it is, of course, essential that treatment be successful but the prophylactic advice offered is often of far greater economic benefit to the cattle owner. In order to give sound advice we must be knowledgeable not only in cattle diseases but also many facets of cattle husbandry; such as breeding, feeding, housing, and hoof trimming.

description: Aims: Modern pharmaceutical product development is a long and complex process associated with significant investments by pharmaceutical companies. The innovative pharmaceutical industry accounts for the vast majority of expenditures in clinical trials of potential new pharmaceuticals and therefore generates economic activity within a country. The aim was to assess the far-reaching economic impact of industry-sponsored clinical-trials (ISCTs) of pharmaceutical products for the healthcare system and the national economy. Materials and methods: The study approach was based on three analytical steps. First, a survey among 15 pharmaceutical companies in Austria was conducted to evaluate the annual number of ISCTs subdivided according to trial phase, therapeutic areas and associated employees. Second, the monetary value of treatments performed in ISCTs was calculated based on a sample of clinical-trial protocols. Finally, the macroeconomic impact, measured in terms of value-added and jobs created by the conducted ISCTs, was calculated using Input–Output analysis by applying an extended Leontief-model. Results: The study demonstrated that €116.22 million spent in ISCTs generated a total value added of €144 million, €74 million direct, in 2018. Each year a medical treatment value of €100 million was financed through 463 ISCTs, with an average value of medical treatment of €37,068 per recruited patient. This represents a significant 0.3% of annual current health-expenditures. In summary, each Euro invested by the pharmaceutical industry in ISCTs generates €1.95 for the Austrian economy. ISCTs also created and secured employment in the extent of 2,021 full-time-equivalents, thus resulting in an employment multiplier of 1.66. Conclusions: In conclusion, conducting clinical-trials by pharmaceutical industry—beside its importance in its own domain—results in tangible benefits and a positive macroeconomic impact that contribute to the sustainability of the Austrian healthcare system by complementing its limited resources. Furthermore, it is a non-negligible factor in locational and industrial policy.

description: The twofold twist defects in the $D(\mathbb{Z}_k)$ quantum double model (abelian topological phase) carry non-abelian fractional Majorana-like characteristics. We align these twist defects in a line and construct a one dimensional Hamiltonian which only includes the pairwise interaction. For the defect chain with even number of twist defects, it is equivalent to the $\mathbb{Z}_k$ clock model with periodic boundary condition (up to some phase factor for boundary term), while for odd number case, it maps to $\mathbb{Z}_k$ clock model with duality twisted boundary condition. At critical point, for both cases, the twist defect chain enjoys an additional translation symmetry, which corresponds to the Kramers-Wannier duality symmetry in the $\mathbb{Z}_k$ clock model and can be generated by a series of braiding operators for twist defects. We further numerically investigate the low energy excitation spectrum for $k=3,~4,~5$ and $6$. For even-defect chain, the critical points are the same as the $\mathbb{Z}_k$ clock conformal field theories (CFTs), while for odd-defect chain, when $k\neq 4$, the critical points correspond to orbifolding a $\mathbb{Z}_2$ symmetry of CFTs of the even-defect chain. For $k=4$ case, we numerically observe some similarity to the $\mathbb{Z}_4$ twist fields in $SU(2)_1/D_4$ orbifold CFT.

description: Aims: To evaluate total costs and health consequences of a colorectal cancer (CRC) screening program with colonoscopy, fecal immunochemical tests (FIT), and expanded use of multitarget stool DNA (mt-sDNA) from the perspectives of Integrated Delivery Networks (IDNs) and payers in the United States. Materials and methods: We developed a budget impact and cost-consequence model that simulates CRC screening for eligible 50- to 75-year-old adults. A status quo scenario and an increased mt-sDNA scenario were modeled. The status quo includes the current screening mix of colonoscopy (83%), FIT (11%), and mt-sDNA (6%) modalities. The increased mt-sDNA scenario increases mt-sDNA utilization to 28% over 10 years. Costs for both the IDN and the payer perspectives incorporated diagnostic and surveillance colonoscopies, adverse events (AEs), and CRC treatment. The IDN perspective included screening program costs, composed of direct nonmedical (e.g. patient navigation) and indirect (e.g. administration) costs. It was assumed that IDNs do not incur the costs for stool-based screening tests or bowel preparation for colonoscopies. Results: In a population of one million covered lives, the 10-year incremental cost savings incurred by increasing mt-sDNA utilization was $19.6 M for the IDN and $4.4 M for the payer. The incremental savings per-person-per-month were $0.16 and $0.04 for the IDN and payer, respectively. For both perspectives, increased diagnostic colonoscopy costs were offset by reductions in screening colonoscopies, surveillance colonoscopies, and AEs. Extending screening eligibility to 45- to 75-year-olds slightly decreased the overall cost savings. Limitations: The natural history of CRC was not simulated; however, many of the utilized parameters were extracted from highly vetted natural history models or published literature. Direct nonmedical and indirect costs for CRC screening programs are applied on a per-person-per modality basis, whereas in reality some of these costs may be fixed. Conclusions: Increased mt-sDNA utilization leads to fewer colonoscopies, less AEs, and lower overall costs for both IDNs and payers, reducing overall screening program costs and increasing the number of cancers detected while maintaining screening adherence rates over 10 years.
