Authors: Morales Sergio , Lam Peter , Cerrato Rebecca , Mococain Pablo , Ruz Cristián , Filippi Jorge , Villa Andrés , Varas Julián 
Published: August 2024

Background:
Minimally invasive surgery (MIS) for hallux valgus (HV) has gained popularity. However, adopting this technique faces the challenges of a pronounced learning curve. This study aimed to address these challenges by developing and validating an innovative simulation model and training program, targeting enhanced proficiency in HV MIS.

Methods:
A training program and a high-fidelity simulation model for HV MIS were designed based on experts' recommendations. Four foot and ankle surgeons without experience in MIS formed the novice group and took the program that encompassed six-session instructional lessons, hands-on practice on simulated models, and immediate feedback. The program concluded with a cadaveric surgery. Four foot and ankle experienced MIS surgeons formed the expert group and underwent the same procedure with one simulated model. Participants underwent blind assessment, including Objective Structured Assessment of Technical Skills (OSATS), surgical time, and radiograph usage.

Results:
Expert evaluation of the simulation model indicated high satisfaction with anatomical representation, handling properties, and utility as a training tool. The expert group consistently outperformed novices at the initial assessment across all outcomes, demonstrating OSATS scores of 24 points (range, 23 to 25) versus 15.5 (range, 12 to 17), median surgical time of 22.75 minutes (range, 12 to 27) versus 48.75 minutes (range, 38 to 60), and median radiograph usage of 70 (range, 53 to 102) versus 232.5 (range, 112 to 280).

Discussion:
Novices exhibited a significant improvement in OSATS scores from the fifth session onward (P = 0.01), reaching the desired performance of 20 points. Performance at the final training with the simulated model did not differ from cadaveric surgery outcomes for all parameters.

Conclusion:
This study validated a simulation model and training program, allowing nonexperienced HV MIS foot and ankle surgeons to enhance their surgical proficiency and effectively complete a substantial portion of the learning curve at the fifth session, and this performance was successfully transferred to a cadaver model.

Authors: Pradoto Wisnu , Safrul Muhammad , Anam Ramli Nurul 
Published: August 2024

The patterns of land utilization and infrastructure investment serve as means that can be employed to create opportunities for increasing the economic value of land. This research aims to formulate a Land Value Capture (LVC) model as a non-government financing source that can be utilized for financing the development of the Pekalongan City Station area with Transit-Oriented Development (TOD) concepts. The analytical tools used include multiple regression analysis, overlay, descriptive and literature studies, as well as SWOT analysis. The study results demonstrate that the distance to the commercial center is the most influential variable in increasing land value. The closer the proximity to the commercial center, the higher the land value will be. Meanwhile, areas considered potential for the application of LVC instruments are the Hoegeng Stadium area, the Ex Sri Ratu area, shops on its east side, and the shops east of the station. LVC instruments that can be applied include land value tax, joint development, land readjustment with diversification strategies.

Representation of Polynomials Over Finite Fields With Circulants
Authors: Muratović Amela 
Published: August 2024

Representation of polynomials over complex fields is well known. In this paper a similar representation is given for polynomials of degree less than $q-1$, over finite fields. The results are theorems that characterize the centralizer of the circulant of a permutation polynomial, and a formula for the calculation of the determinant of the circulant as the product of the determinants of the polynomials defined on the cosets of some multilpicative subgroup.

Authors: Fatkić Huse 
Published: August 2024

Let ($S, \mathfrak{A}, \mu$) be a finite measure space and let $\phi: S \rightarrow S$ be a transformation which preserves the measure $\mu$. The purpose of this paper is to give some (measure theoretical) necessary and sufficient conditions for the transformation $\phi$ to be measurability-preserving ergodic with respect to $\mu$. The obtained results extend well-known results for invertible ergodic transformations and complement the previous work of R.E. Rice on measurability-preserving strong-mixing transformations.

A Convolution Related to the Inverse Kontorovich-Lebedev Transform
Authors: Yakubovich S. B. , Britvina L. E. 
Published: August 2024

We establish the mapping properties in the space $L_2({\mathbbR}_+;\frac{dt}{t\sinh \nu t})$, $0<\nu\le\pi$ for a convolution related to the transformation\[F(x)=\int\limits_0^\infty f(t) K_{it}(x)\,dt, \quad x\in{\mathbb R}_{+}\]involving the modified Bessel function $K_{it}(x)$ as a kernel. It is shown that the convolution operator of two $L_2$-functions exists as a Lebesgue integral and represents a continuous function on ${\mathbb R}_+$. As a consequence, we get the multiplication theorem for two modified Bessel functions of different subscripts. Further applications to the corresponding class of convolution integral equations are obtained.

Representation Theorems for Connected Compact Hausdorff Spaces
Authors: Džamonja Mirna 
Published: August 2024

We present two theorems which can be used to represent compact connected Hausdorff spaces in an algebraic context, using a Stone-like representation. The first theorem stems from the work of Wallman and shows that every distributive disjunctive normal lattice is the lattice of closed sets in a unique up to homeomorphism connected compact Hausdorff space. The second theorem stems from the work of Jung and Sünderhauf. Introducing the notion of strong proximity involution lattices, it shows that every such lattice can be uniquely represented as the lattice of pairs of compact and open sets of connected compact Hausdorff space. As a consequence we easily obtain a somewhat surprising theorem birepresenting distributive disjunctive normal lattices and strong proximity involution lattices.

More on Hurwitz and Tasoev Continued Fractions
Authors: Komatsu Takao 
Published: August 2024

Several new types of Hurwitz continued fractions have been studied. Most basic Hurwitz continued fractions can be expressed by using confluent hypergeometric functions ${}_0F_1(;c;z)$. This expression enables us to find some more general Hurwitz continued fractions. A contrast between Tasoev continued fractions and Hurwitz ones yields some more general Tasoev continued fractions. Some Ramanujan continued fractions are also discussed.

On the Topological Nature of the Stable Sets Associated to the Second Invariant of the Order $q$ Standard Lyness’ Equation
Authors: Bastien G. , Rogalski M. 
Published: August 2024

We prove a conjecture asserted in a previous paper (see [2]) about order $q$ Lyness difference equation in ${\mathbb R}_*^+$:$u_{n+q}\,u_n=a+u_{n+q-1}+{\dots}+u_{n+1}$, with $a>0$. It is known that the function on ${{\mathbb R}_*^+}^q$ defined by\begin{multline*}H(x)=\frac{(1+x_1+x_2)(1+x_2+x_3)\dots}{x_1\dots x_q}\\\frac{(1+x_{q-1}+x_q)(a+x_1x_q+x_1+x_2+{\dots}+x_q)}{ x_1\dotsx_q}\end{multline*}is an {\sl invariant} for this equation. It is conjectured in [2] (and proved for $q=3$ only) that if $M>M_a:=\min H$ is {\sl sufficiently near} to $M_a$, then the set $S(M):=\{x\,|\,H(x)=M\}$ is homeomorphic to the sphere $\mathbbS$$^{^{q-1}}$. Here we prove this conjecture for every $q\geq 3$, and deduce from it that if the equilibrium $L$ of the map $T$ associated to the Lyness' equation, where $H$ attains its minimum, is for some $q$ {\sl the only critical point} of $H$, then the sets $S(M)$ are, for this $q$, homeomorphic to $\mathbbS$$^{^{q-1}}$ for every $M>M_a$, and that this is the case for $q$=3, 4 or 5.

Published: August 2024

In Section 2 we shall prove that if Cartesian product $X\times Y$ of nondegenerate continua admits a hereditarily irreducible mapping $f:X\times Y\rightarrow Z,$ then w$(X\times Y)$=w$(Z)$.
The main section of the paper, Section 3, contains theorems concerning the Whitney maps on continua. In particular, it is proved that the product $\Pi \{X_{s}:s\in S\}$ of nondegenerate continua admits a Whitney map for $C(\Pi \{X_{s}:s\in S\})$ if and only if it is metrizable.
