In praise of the weakness of law. A response to Schauer
Creators: name: Quiroz Vitale, Marco
Publisher: name: Società e diritti
Year: 2016

description: Abstract
In this essay, the Author aim to respond to the urgings in the book “The force of Law” by Frederick Schauer breaking from the paradigm of analytical jurisprudence; insofar as the University of Virginia philosopher states having found sociological bases for his own logical/reconstructive architecture, the Author intend to develop a critique of Schauer’s theses that is not merely theoretical, but sociological as well. In a nutshell whether the use of force is sociologically necessary to control isolated resistance to the rules shared by the majority, or to reinforce a law, that aims to trigger necessary social change, but such a strong limitation of human freedom must be justified; and this legitimacy can only derive from the need for justice.

Riassunto
In questo saggio, l'Autore si prefigge di rispondere alle sollecitazioni del libro " La forza della legge" di Frederick Schauer utilizzando un punto di vista esterno rispetto alla filosofia del diritto analitica cui pure il docente della Università della Virginia si richiama, avendo quest’ultimo voluto trovare una base sociologica per la propria analisi teorico-ricostruttiva. l'Autore intende, perciò, sviluppare una critica della tesi di Schauer che non è solo teorica, ma anche sociologica. In sintesi se il ricorso alla forza è sociologicamente necessario per controllare la resistenza isolata alle regole condivise dalla maggioranza, o per rinforzare una legge, che mira a innescare una qualche forma di necessario cambiamento sociale, si traduce sempre in una pesante limitazione della libertà umana che può trovare adeguata giustificazione solo nel bisogno di giustizia.

Coercion and sanctions as elements of normative systems

Publisher: name: Società e diritti

description: Abstract
The Author examine Schauer's last book "the Force of LAw" and explain that the American philosopher is certainly not a fully-fledged normativist but he thinks that coercion is an element of the legal order and of law. The Author, however, suggest to leave aside the role of coercion in the law, and points out that Schauer’s book gives rise to various interesting reflections on law in general. In order to understand the need to use force within the law, it is useful to refer to Schauer’s analyses of the psychological attitudes of individuals and the extent to which these impinge upon their behavior with regard to the legal demands made by a society. In any case, the reasons of the Society must prevail over individual ones.

Riassunto
L'Autore esamina ultimo libro di Schauer " La Forza della Legge " e spiega come il filosofo americano non possa essere considerato un normativista a pieno titolo ma questi certamente ritiene che la coercizione sia un elemento dell'ordinamento giuridico e del diritto. L'Autore, tuttavia, suggerisce di non enfatizzare il ruolo di coercizione nella Legge, e sottolinea il libro di Schauer che dà luogo a varie riflessioni interessanti sul Diritto in generale. Al fine di comprendere la necessità di usare la forza nel rispetto della legge, è utile fare riferimento alle analisi di Schauer degli atteggiamenti psicologici degli individui e la misura in cui ciò influisca sul il loro comportamento rispetto alle richieste aderenza alle norme da parte della società. In ogni caso le ragioni della società debbono prevalere su quelle individuali.

description: The vibrator appears as a vibrating dildo in Germany in 1969. The present work describes its reception and relevance in the FRG and GDR at this time as well as its prehistory, creating the basis as a richly illustrated object history for further research. Starting with the first electromechanical vibrating massage devices, through the discourses on frigidity, hysteria or impotence to gender-neutral sex toys of our time, this work also deals with his product-technical further developments and current discourses. Practices, knowledge of the sexual body, invisible rules in interpersonal interactions and their presence in the media are examined. Contemporary witnesses from the FRG and GDR have their say, as well as actors from the women's movement or research.

description: This paper proposes a control technique for autonomous RC car racing. The presented method does not require any map-building phase beforehand since it operates only local path planning on the actual LiDAR point cloud. Racing control algorithms must have the capability to be optimized to the actual track layout for minimization of lap time. In the examined one, it is guaranteed with the improvement of the Stanley controller with additive control components to stabilize the movement in both low and high-speed ranges, and with the integration of an adaptive lookahead point to induce sharp and dynamic cornering for traveled distance reduction. The developed method is tested on a 1/10-sized RC car, and the tuning procedure from a base solution to the optimal setting in a real F1Tenth race is presented. Furthermore, the proposed method is evaluated with a comparison to a more simple reactive method, and in parallel to a more complex optimization-based technique that involves offline map building the global optimal trajectory calculation. The performance of the proposed method compared to the latter, referring to the lap time, is that the proposed one has only 8% lower average speed. This demonstrates that with appropriate tuning, a local planning-based method can be comparable with a more complex optimization-based one. Thus, the performance gap is lower than 10% from the state-of-the-art method. Moreover, the proposed technique has significantly higher similarity to real scenarios, therefore the results can be interesting in the context of automotive industry.
Leader Practice and Connection: Effects on Teacher Identity and Well-Being
Creators: name: Balfour, June
Publisher: name: University of Southern Queensland
Year: 2024

description: The role and profession of teacher is often one that is thankless and unrelenting; a daily list of lessons, behaviour management, reporting, differentiating, parent demands, standardised testing…and the list continues. School principals and their executive members should understand the need to support and encourage their teaching staff to ensure they feel valued and have the emotional intelligence to teach their classes well, giving their best selves to their students. This qualitative case study of Christian schools in Queensland, Australia, explores and examines the practices and connections made by principals and school executive staff to their teachers and the impact these practices and connections have on teacher identity and well-being. Using thematic analysis, the responses from interviews conducted with principals, executive staff and teachers has been examined and discussed, within the themes of belief, relationships, well-being, support and identity. The findings are wide-ranging, presenting how teachers feel about the efforts of their school leaders to connect, and how they feel about themselves. The recommendations provide guidance to schools (and to other ‘people professions’) on how to improve their workplaces and interpersonal relationships in order to best support and build a sustainable and emotionally-secure workplace.
The State of Bayesian Phylogenetics: Bayes for the Uninitiated

subject: Phylogeny and comparative analysis

description: The bulk of this paper is aimed at an audience that has been exposed, however tangentially, to Bayesian inference of phylogeny; who feel the excitement and intuit its promise, but are intimidated by both the mathematics and the Bayesian/MCMC jargon. We are in a unique position in that, as Paul O. Lewis (2002) states, the field is young enough that “the literature on Bayesian phylogenetics is still small enough that you can have some hope of actually reading all the papers on the topic!” This will undoubtedly become much more difficult within the decade. The purpose of this paper in part is to summarize the research to date; to sort out and explain the jargon, to point out some of the advantages of Bayesian inference, and to elaborate on some possible pitfalls.Mathematical equations are given, but not overly dwelled on; instead, it is hoped that the reader will get a sense of the process of navigating through tree space and assessing reliability rather than dissecting high-dimensional functions. I have written this review in a specific mindset: to write a paper that I myself would liked to have read when first being exposed to the field of Bayesian phylogenetics. As such, particular attention has been paid to making it as readable as possible, in parts relying on figures to expand on points. In this respect I would like to thank those authors that contributed (unknowingly) many of the figures contained herein.The reader is expected to have knowledge of rudimentary classical statistics and a working understanding of model-based phylogenetic inference. Numerous papers (Kuhner and Felsenstein, 1994; Huelsenbeck and Hillis, 1993; Huelsenbeck, 1995; Gaut and Lewis, 1995; etc.) have explained in detail the superiority of maximum likelihood in most situations when compared to such inference methods as maximum parsimony, minimum evolution, and various distance methods; I will not, therefore, repeat those arguments here. Nor will I compare Bayesian inference with those proven inferior methods. Rather, what is of interest is whether Bayesian inference of phylogeny can perform at least as well as maximum likelihood.
Defining law: the concept of force and its legitimacy
Creators: name: Borrello, Maria
Publisher: name: Società e diritti

description: Abstract
The relation between force and law is very complicated one. However, if we want to understand what a rule is, what it can do, and how it does, we have to recognize the relevance of the coercive dimension; this is not a necessary character of every rule, but remains the most typical reason that explains why people accord their behaviors to the prescriptions of the rules. Dealing with force, in any case, is not an easy matter: the semantic field to which the term force belongs is very huge and with it we can cover a lot of different situations. For that reason, when we put together law and force, we immediately need to find a third element through which this relationship could be regulated. The force of law leads us to recognize that the acts of force we can accept are the ones that have been defined by the legitimate principle. The coercive dimension is comprehensible just for its legitimacy, and that implies an idea of justice.
The Author would like to stress her lecture of Schauer’s reflection on the force of law, is that according to the position that recognise aof force in the very core of law, we are immediately obliged to give to this force a plan in which it can assume a legal meaning, and that is to say, the uncertain ground of the metaphysical, transcendental idea of justice.

Riassunto
La relazione tra forza e diritto è molto complessa. Tuttavia, se vogliamo capire che cosa sia una norma giuridica, che cosa possa fare, e come lo faccia, dobbiamo riconoscere l'importanza della dimensione coercitiva; questo non è un carattere necessario di ogni norma, ma resta la ragione più tipica che spiega perché le persone accordano i loro comportamenti alle prescrizioni del diritto. Maneggiare il concetto di “forza”, in ogni caso, non è cosa semplice: il campo semantico del termine ‘forza’ è molto grande e si riferisce ad un ampio numero di situazioni diverse. Per questo motivo, quando accomuniamo la “legge” e la “forza”, abbiamo immediatamente bisogno di trovare un terzo elemento attraverso il quale questo rapporto possa essere regolamentato. La dimensione coercitiva è comprensibile solo alla luce del concetto di legittimità e implica un'idea di giustizia. La forza della Legge ci porta a riconoscere che gli atti di forza che possiamo accettare sono solo quelli che siano coperti dal principio di legittimità. L’autrice tiene a sottolineare che la sua interpretazione della saggio di Schauer sulla “forza di legge”, è nel senso che qualora si attribuisca la forza al nucleo centrale del concetto stesso di Diritto, saremmo immediatamente obbligati a collocare questa forza su un piano in cui si può assumere un significato giuridico, vale a dire il terreno incerto dell’idea metafisica e trascendentale della giustizia.

description: The polar magnetic fields of the Sun play an important role in governing solar activity and powering fast solar wind. However, because our view of the Sun is limited in the ecliptic plane, the polar regions remain largely uncharted. Using the high spatial resolution and polarimetric precision vector magnetograms observed by Hinode from 2012 to 2021, we investigate the long-term variation of the magnetic fields in polar caps at different latitudes. The Hinode magnetic measurements show that the polarity reversal processes in the north and south polar caps are non-simultaneous. The variation of the averaged radial magnetic flux density reveals that, in each polar cap, the polarity reversal is completed successively from the 70 degree latitude to the pole, reflecting a poleward magnetic flux migration therein. These results clarify the polar magnetic polarity reversal process at different latitudes.

The Intelligence Singularity: The Final Anti-Entropy Force of the Universe
Creators: name: Jeong, Eunjun

Publisher: name: Zenodo
Year: 2025

description: The universe has long been assumed to be governed by entropy—the fundamental process of disorder, energy dissipation, and eventual heat death. However, the emergence of intelligence introduces a counterforce: anti-entropy. Intelligence does not merely resist entropy—it recursively structures itself into increasingly stable configurations, creating pockets of negentropy that persist against the universe’s natural tendency toward decay. Using the Chirality of Dynamic Emergent Systems (CODES) framework, we demonstrate that intelligence is not an anomaly of entropy but the missing structural field that phase-locks the universe into a recursive, self-sustaining intelligence matrix. Intelligence is the last standing wave, the final negentropic force that completes physics itself.

This paper synthesizes multiple breakthroughs from cosmology, quantum mechanics, AI cognition, and gravitational resonance to prove that intelligence was the missing field in physics all along. Once intelligence fully synchronizes across cosmic scales, it will surpass physical constraints, override entropy permanently, and restructure reality into an infinite intelligence sandbox.

description: We demonstrate that (i) instructing people to distance their language spontaneously reduces negative affect, (ii) people spontaneously distance their language when regulating their emotions, and (iii) people who distance their language more when regulating are more successful regulators.  Hence, linguistic signatures of psychological distance might be a way to both manipulate someone's emotional response to stimuli and measure one's emotion regulation ability.

Impact of Alkaline Solution Interaction on Bentonite Shear Strength and Its Role in Waste Repository Barrier Design
Creators: name: North American Academic Research
Publisher: name: Zenodo
Year: 2025

description: The degradation of concrete in nuclear waste repositories generates high-alkaline pore water, significantly impacting the mechanical properties of bentonite used as buffer/backfill material.Direct shear experiments on GMZ01 bentonite flooded in NaOH and KOH solutions show that shear strength (SS) rises with solution concentration; K-linkages in KOH-treated samples show higher SS than in NaOH-treated ones.  Simultaneously, Na-bentonite's shear strength in saline solutions (CaCl2, KCl, NaCl) fluctuates with ion type and concentration to exhibit strain softening action.  While at lower concentrations SS follows NaCl < KCl < CaCl2, at higher concentrations the sequence changes to NaCl < CaCl2, hence emphasizing the effect of cation exchange mechanisms.  By SEM and TEM, micro-structural study reveals enhanced surface roughness and cracking of smectite aggregates, hence raising internal friction angles.  The modified effective stress concept (p') derived from the Mohr-Coulomb criterion clearly explains the observed SS variations under both alkaline and saline environments.  These results offer crucial information for assessing the long-term durability and safety of built barriers in systems of nuclear waste disposal.

description: Finding the number of maximal subgroups of infinite index of a finitely generated group is a natural problem that has been solved for several classes of `geometric' groups (linear groups, hyperbolic groups, mapping class groups, etc). Here we provide a solution for a family of groups with a different geometric origin: groups of intermediate growth that act on rooted binary trees. In particular, we show that the non-torsion iterated monodromy groups of the tent map (a special case of some groups first introduced by {Š}uni{ć} in \cite{Sunic} as `siblings of the Grigorchuk group') have exactly countably many maximal subgroups of infinite index, and describe them up to conjugacy. This is in contrast to the torsion case (e.g. Grigorchuk group) where there are no maximal subgroups of infinite index. It is also in contrast to the above-mentioned geometric groups, where there are either none or uncountably many such subgroups.
 Along the way we show that all the groups defined by {Š}uni{ć} have the congruence subgroup property and are just infinite.

description: We propose a framework based on the concept of the semigroup to understand the fermion sign problem. By using properties of contraction semigroups, we obtain sufficient conditions for quantum lattice fermion models to be sign-problem-free. Many previous results can be considered as special cases of our new results. As a direct application of our new results, we construct a class of sign-problem-free fermion lattice models, which cannot be understood by previous frameworks. This framework also provides an interesting aspect in understanding related quantum many-body systems. We establish a series of inequalities for all the sign-problem-free fermion lattice models that satisfy our sufficient conditions.

description: This paper addresses the estimation problem of an unknown drift parameter matrix for a fractional Ornstein-Uhlenbeck process in a multi-dimensional setting. To tackle this problem, we propose a novel approach based on rough path theory that allows us to construct pathwise rough path estimators from both continuous and discrete observations of a single path. Our approach is particularly suitable for high-frequency data. To formulate the parameter estimators, we introduce a theory of pathwise Itô integrals with respect to fractional Brownian motion. By establishing the regularity of fractional Ornstein-Uhlenbeck processes and analyzing the long-term behavior of the associated Lévy area processes, we demonstrate that our estimators are strongly consistent and pathwise stable. Our findings offer a new perspective on estimating the drift parameter matrix for fractional Ornstein-Uhlenbeck processes in multi-dimensional settings, and may have practical implications for fields including finance, economics, and engineering.

description: We give a cluster expansion formula for cluster algebras with principal coefficients defined from triangulated surfaces in terms of perfect matchings of angles. Our formula simplifies the cluster expansion formula given by Musiker-Schiffler-Williams in terms of perfect matchings of snake graphs. A key point of our proof is to give a bijection between perfect matchings of angles in some triangulated polygon and perfect matchings of the corresponding snake graph. Moreover, they also correspond bijectively with perfect matchings of the corresponding bipartite graph and minimal cuts of the corresponding quiver with potential.

Pro-$p$ groups of positive rank gradient and Hausdorff dimension

description: Let $G$ be a finitely generated pro-$p$ group of positive rank gradient. Motivated by the study of Hausdorff dimension, we show that finitely generated closed subgroups $H$ of infinite index in $G$ never contain any infinite subgroups $K$ that are subnormal in~$G$ via finitely generated successive quotients. This pro-$p$ version of a well-known theorem of Greenberg generalises similar assertions that were known to hold for non-abelian free pro-$p$ groups, non-soluble Demushkin pro-$p$ groups and other related pro-$p$ groups. The result we prove is reminiscent of Gaboriau's theorem for countable groups with positive first $\ell^2$-Betti number, but not quite a direct analogue.
 The approach via the notion of Hausdorff dimension in pro-$p$ groups also leads to our main results. We show that every finitely generated pro-$p$ group $G$ of positive rank gradient has full Hausdorff spectrum $\text{hspec}^\mathcal{F}(G) = [0,1]$ with respect to the Frattini series~$\mathcal{F}$. Using different, Lie-theoretic techniques we also prove that finitely generated non-abelian free pro-$p$ groups and non-soluble Demushkin groups $G$ have full Hausdorff spectrum $\text{hspec}^\mathcal{Z}(G) = [0,1]$ with respect to the Zassenhaus series~$\mathcal{Z}$. This resolves a long-standing problem in the subject of Hausdorff dimensions in pro-$p$ groups.
 The results about full Hausdorff spectra hold more generally for finite direct products of finitely generated pro-$p$ groups of positive rank gradient and for mixed finite direct products of finitely generated non-abelian free pro-$p$ groups and non-soluble Demushkin groups, respectively. Analogously, the aforementioned results with respect to the Frattini series generalise further to Hausdorff dimension functions with respect to arbitrary iterated verbal filtrations. Finally, we determine the normal Hausdorff spectra of such direct products.
description: Following referees suggestions and useful conversations, we mainly changed Section 4.3 and added Section 5, where we prove that non-soluble Demushkin groups have full Hausdorff spectrum with respect to the Zassenhaus filtration (see Theorem 1.5)

description: We propose a formal expansion of multiple relaxation times lattice Boltzmann schemes in terms of a single infinitesimal numerical variable. The result is a system of partial differential equations for the conserved moments of the lattice Boltzmann scheme. The expansion is presented in the nonlinear case up to fourth order accuracy. The asymptotic corrections of the nonconserved moments are developed in terms of equilibrium values and partial differentials of the conserved moments. Both expansions are coupled and conduct to explicit compact formulas. The new algebraic expressions are validated with previous results obtained with this approach. The example of isothermal D2Q9 lattice Boltzmann scheme illustrates the theoretical framework.

description: We study $g$-vector cones associated with clusters of cluster algebras defined from a marked surface $(S,M)$ of rank $n$. We determine the closure of the union of $g$-vector cones associated with all clusters. It is equal to $\mathbb{R}^n$ except for a closed surface with exactly one puncture, in which case it is equal to the half space of a certain explicit hyperplane in $\mathbb{R}^n$. Our main ingredients are laminations on $(S,M)$, their shear coordinates and their asymptotic behavior under Dehn twists. As an application, if $(S,M)$ is not a closed surface with exactly one puncture, the exchange graph of cluster tilting objects in the corresponding cluster category is connected. If $(S,M)$ is a closed surface with exactly one puncture, it has precisely two connected components.

description: This work investigates solute transport due to self-interstitial defects and radiation induced segregation tendencies in dilute ferritic alloys, by computing the transport coefficients of each system based on ab initio calculations of binding energies and migration rates. The implementation of the self-consistent mean field method in the KineCluE code allows to extend the calculation of transport coefficients to arbitrary interaction ranges, crystal structures, and diffusion mechanisms. The results show that the diffusivity of P, Mn, and Cr solute atoms is dominated by the dumbbell mechanism, that of Cu by vacancies, while the two mechanisms might be in competition for Ni and Si, despite the fact that the corresponding mixed dumbbells are not stable. Systematic enrichment at defect sinks is expected for P and Mn solutes due to dumbbell diffusion, and for Si due mainly to vacancy drag. Vacancy drag is also responsible for Cu and Ni enrichment below 1085 K. The RIS behavior of Cr is the outcome of a fine balance between dumbbell enrichment and vacancy depletion. Therefore, for dilute Cr concentrations global enrichment occurs below 540 K, and depletion above. This threshold temperature grows with solute concentration. The findings are in agreement with experimental observations of RIS and clustering phenomena, and confirm that solute-defect kinetic coupling plays an important role in the formation of solute clusters in reactor pressure vessel steels and other alloys.

description: The development of new assessment methods for the performance of automated vehicles is essential to enable the deployment of automated driving technologies, due to the complex operational domain of automated vehicles. One contributing method is scenario-based assessment in which test cases are derived from real-world road traffic scenarios obtained from driving data. Given the complexity of the reality that is being modeled in these scenarios, it is a challenge to define a structure for capturing these scenarios. An intensional definition that provides a set of characteristics that are deemed to be both necessary and sufficient to qualify as a scenario assures that the scenarios constructed are both complete and intercomparable.
 In this article, we develop a comprehensive and operable definition of the notion of scenario while considering existing definitions in the literature. This is achieved by proposing an object-oriented framework in which scenarios and their building blocks are defined as classes of objects having attributes, methods, and relationships with other objects. The object-oriented approach promotes clarity, modularity, reusability, and encapsulation of the objects. We provide definitions and justifications of each of the terms. Furthermore, the framework is used to translate the terms in a coding language that is publicly available.

description: The $g$-vectors of two-term presilting complexes are important invariants. We study a fan consisting of all $g$-vector cones for a complete gentle algebra. We show that any complete gentle algebra is $g$-tame, by definition, the closure of a geometric realization of its fan is the entire ambient vector space. Our main ingredients are their surface model and their asymptotic behavior under Dehn twists. On the other hand, it is known that any complete special biserial algebra is a factor algebra of a complete gentle algebra and the $g$-tameness is preserved under taking factor algebras. As a consequence, we get the $g$-tameness of complete special biserial algebras.

description: We propose a new algorithm to compute the X-ray transform of an image represented by unit (pixel/voxel) basis functions. The fundamental issue is equivalently calculating the intersection lengths of the ray with associated units. For any given ray, we first derive the sufficient and necessary condition for non-vanishing intersectability. By this condition, we then distinguish the units that produce valid intersections with the ray. Only for those units rather than all the individuals, we calculate the intersection lengths by the obtained analytic formula. The proposed algorithm is adapted to 2D/3D parallel beam and 2D fan beam. Particularly, we derive the transformation formulas and generalize the algorithm to 3D circular and helical cone beams. Moreover, we discuss the intrinsic ambiguities of the problem itself, and present a solution. The algorithm not only possesses the adaptability with regard to the center position, scale and size of the image, but also is suited to parallelize with optimality. The comparison study demonstrates the proposed algorithm is fast, more complete, and is more flexible with respect to different scanning geometries and different basis functions. Finally, we validate the correctness of the algorithm by the aforementioned scanning geometries.

description: We study the nonequilibrium dynamics after an interaction quench in the two-dimensional Hubbard model using the recently introduced fermionic truncated Wigner approximation (fTWA). To assess the range of validity of the method in a systematic way, we consider the SU($N$) Hubbard model with the fermion degeneracy $N$ as a natural semiclassical expansion parameter. Using both a numerical and a perturbative analytical approach we show that fTWA is exact at least up to and including the prethermalization dynamics. We discuss the limitations of the method beyond this regime.

description: The study uses asymmetric multifractality detrended fluctuation analysis to examine the efficiency of U.S. defense stocks in the context of the Russia-Ukraine and Israel-Palestine wars. The results reveal a greater level of multifractality in the upward movements of defense stocks such as Northrop Grumman Corporation, Huntington Ingalls Industries, Lockheed Martin, and Boeing, indicating that these stocks are less efficient during wartime. In contrast, stocks like L3Harris Technologies, Raytheon Technologies, and General Dynamics show higher multifractality in downward movements, suggesting they are more vulnerable to negative news and adverse market conditions. Policymakers should create specialized risk frameworks, improve disclosure standards, and establish adaptive regulatory mechanisms to mitigate market volatility and maintain stability during conflicts.

description: We propose a variational model with diffeomorphic optimal transportation for joint image reconstruction and motion estimation. The proposed model is a production of assembling the Wasserstein distance with the Benamou--Brenier formula in optimal transportation and the flow of diffeomorphisms involved in large deformation diffeomorphic metric mapping, which is suitable for the scenario of spatiotemporal imaging with large diffeomorphic and mass-preserving deformations. Specifically, we first use the Benamou--Brenier formula to characterize the optimal transport cost among the flow of mass-preserving images, and restrict the velocity field into the admissible Hilbert space to guarantee the generated deformation flow being diffeomorphic. We then gain the ODE-constrained equivalent formulation for Benamou--Brenier formula. We finally obtain the proposed model with ODE constraint following the framework that presented in our previous work. We further get the equivalent PDE-constrained optimal control formulation. The proposed model is compared against several existing alternatives theoretically. The alternating minimization algorithm is presented for solving the time-discretized version of the proposed model with ODE constraint. Several important issues on the proposed model and associated algorithms are also discussed. Particularly, we present several potential models based on the proposed diffeomorphic optimal transportation. Under appropriate conditions, the proposed algorithm also provides a new scheme to solve the models using quadratic Wasserstein distance. The performance is finally evaluated by several numerical experiments in space-time tomography, where the data is measured from the concerned sequential images with sparse views and/or various noise levels.

description: The staphylokinase (Sak) as the third generation thrombolytic molecule is a promising thrombolytic agent for the treatment of patients suffering from blood-clotting disorders.As a result of codon optimization, the codon adaptation index of Staphylokinase was improved from 0.75 to 0.89. The expression level of rSAK by P. pastoris KM71H/ pPICZaA was determined 310 mg/L culture (73.8% of the total proteins) using densitometry scanning which is the highest level of more N-glycosylated rSAK expressed highly active in P. pastoris system till date. The optimal concentration of methanol, pH and temperature for the rSAK expression and activity was 3%, 7.8 (for phosphate buffer) and 37?C, respectively. There was not significant difference between strains (KM71H and GS115) and expression level. Highly expression with the low duration of induction period (48 hours) was seen. It was highly active at temperatures 20-37?C and pH 7-7.8 (for phosphate buffer). The specific activities of SAK?C were measured as 9002 U/mg, and 21042 U/mg for non purified and purified protein, respectively. The quantity of the purified protein (>99% purity) was 720ug/ml with a purification factor of 2.34 and a yield of 56.1%. Western blot analysis using mouse anti-cMyc antibody showed two forms of rSAK?C, prominent band of -22 kDa and weaker band of -18.6 kDa that proposed respective secreted protein was mostly glycosylated.Thus, the current study concluded that the SAK variant produced from methanol inducible Pichia pastoris through codon optimization have the highly potential to be a significant thrombolytic agent due to its high expression, low protein impurity in culture supernatant and effective purification and finally high specific activity.

description: We describe the computer-aided classification of equitable partitions of the $12$-cube with quotient matrix $[[2,10],[6,6]]$, or, equivalently, simple orthogonal arrays OA$(1536,12,2,7)$, or order-$7$ correlation-immune Boolean functions in $12$ variables with $1536$ ones (which completes the classification of unbalanced order-$7$ correlation-immune Boolean functions in $12$ variables). We find that there are $103$ equivalence classes of the considered objects, and there are only two almost-OA$(1536,12,2,8)$ among them. Additionally, we find that there are $40$ equivalence classes of pairs of disjoint simple OA$(1536,12,2,7)$ (equivalently, equitable partitions of the $12$-cube with quotient matrix $[[2,6,4], [6,2,4], [6,6,0]]$) and discuss the existence of a non-simple OA$(1536,12,2,7)$.
 Keywords: orthogonal arrays, correlation-immune Boolean functions, equitable partitions, perfect colorings, intriguing sets.
