A Mathematical Model Of Juvenile Delinquency In The New York State, Oluwasegun Micheal Ibrahim

Articles

This report presents a mathematical model of juvenile delinquency in the New York State. In particular, we develop a juvenile delinquency system of non-linear differential equations using the mathematical epidemiology framework. In constructing this model, we assume that juvenile delinquency can be studied as a socially infectious disease. The stability of the juvenile delinquency-free equilibrium of the model is examined using the standard non-linear dynamical systems theory technique. We carried out a data fitting based on real-life data from the New York State Criminal Justice Services. The research result reveals that the formulated model conforms with the available data and …

Analysis Of Strain Correction Procedures For Single Fiber Tensile Testing, Amy Engelbrecht-Wiggans, Amanda L. Forster

Articles

Accurate strain measurement for single fibers is critical for many engineering applications. Typically, the crosshead displacement is used to calculate strain when performing mechanical testing, however there are complicating factors: slack in the specimen or slipping/seating in the grips, other grip effects, and load frame compliance. These are addressed in various testing standards for single fibers, such as ASTM Standards D3822, “Standard Test Method for Tensile Properties of Single Textile Fibers” and C1557, “Standard Test Method for Tensile Strength and Young's Modulus of Fibers”. In this work, an analysis of single fiber test data has been performed to examine both …

Articles

Films were fabricated using the button mushroom (Agaricus bisporus) sourced high molecular weight chitosan with or without potato starch using the casting method. Glycerol was used as the plasticizer. Chitosan content in the film-forming solution (FFS) was varied (0.5, 0.75 and 1.0% w/v of FFS) while potato starch (1.0% of FFS) and glycerol (25% of the total solid content in the solution) contents were not varied. The control sample contained only chitosan (1.0% of the FFS) and glycerol. The effect of increasing the content of chitosan on the rheological properties of FFS and the properties of the films were investigated. …

Unprecedented Precedent And Original Originalism: How The Supreme Court’S Decision In Dobbs Threatens Privacy And Free Speech Rights, Leonard Niehoff

Articles

The U.S. Supreme Court’s decision in Dobbs v. Jackson Women’s Health Organization has drawn considerable attention because of its reversal of Roe v. Wade and its rejection of a woman’s constitutional right to terminate her pregnancy. The Dobbs majority, and some of the concurring opinions, emphasized that the ruling was a narrow one. Nevertheless, there are reasons to think the influence of Dobbs may extend far beyond the specific constitutional issue the case addresses.

This article explains why Dobbs could have significant and unanticipated implications for the law of privacy and the law of free expression. I argue that two …

The Supreme Court’s 2022–23 Term included a number of important statutory interpretation rulings, as well as significant cases concerning the scope of the Confrontation Clause; the Venue, Vicinage, and Double Jeopardy Clauses; the federal courts’ ability to entertain claims of legal innocence; and the contours of the adequate and independent state ground doctrine. It also was the first term for Justice Ketanji Brown Jackson—the first former public defender and first Black woman to join the centuries-old institution. Although Justice Jackson joined a Court ruptured along ideological lines and confronting serious challenges to its legitimacy and ethical standards, she quickly proved …

The Great Regulatory Dodge, Helen Nissenbaum, Katherine Strandburg, Salome Viljoen

Articles

U.S. privacy law is in a renewed moment of regulatory possibility, with both Congress and the states considering sweeping consumer privacy laws. These new proposals to enact “omnibus” privacy protections could be couched as an antidote to the current U.S. privacy regime: a patchwork of sectoral privacy laws stitched atop the background of FTC consumer contract enforcement. However, this Essay maintains that a one-size-fits-all approach cannot successfully capture both privacy’s value and its variability. Yet, it is clearly the case that the present- day sectoral regime in the United States suffers from significant shortcomings. These shortcomings allow behaviors that seem …

Factor Substitution Possibilities, Labor Share Dynamics, And Inequality In An Age Of Intangibles, Adnan Velic

Articles

We examine the economy-wide degree of substitutability between intangible capital and other factor inputs in production using a large sample of advanced countries. In this context, we turn to studying the implications of intangible and tangible capital growth for labor income share dynamics. Compared to tangible capital, we find that intangible capital more strongly complements skilled labor. The analysis further indicates relative fungibility between tangible capital and a composite of intangible capital and skilled labor, in line with the rising prominence of knowledge-intensive tasks and AI-driven online platforms. The intrinsic nature of intangibles and their asymmetric effects across skilled and …

New Fxlmat-Based Algorithms For Active Control Of Impulsive Noise, Alina Mirza, Farkhanda Afzal, Ayesha Zeb, Abdul Wakeel, Waqar Shahid Qureshi, Ali Akgul

Articles

In the presence of non-Gaussian impulsive noise (IN) with a heavy tail, active noise control (ANC) algorithms often encounter stability problems. While adaptive filters based on the higher-order error power principle have shown improved filtering capability compared to the least mean square family algorithms for IN, however, the performance of the filtered-x least mean absolute third (FxLMAT) algorithm tends to degrade under high impulses. To address this issue, this paper proposes three modifications to enhance the performance of the FxLMAT algorithm for IN. To improve stability, the first alteration i.e. variable step size FxLMAT (VSSFxLMAT)algorithm is suggested that incorporates the …

Nonlinear Two-Dimensional Water Waves With Arbitrary Vorticity, Delia Ionescu-Kruse, Rossen Ivanov

Articles

We consider the two-dimensional water-wave problem with a general non-zero vorticity field in a fluid volume with a flat bed and a free surface. The nonlinear equations of motion for the chosen surface and volume variables are expressed with the aid of the Dirichlet-Neumann operator and the Green function of the Laplace operator in the fluid domain. Moreover, we provide new explicit expressions for both objects. The field of a point vortex and its interaction with the free surface is studied as an example. In the small-amplitude long-wave Boussinesq and KdV regimes, we obtain appropriate systems of coupled equations for …

Turbulence Phenomena In Magnetohydrodynamic Phase Transitions, Giovambattista Amendola, Mauro Fabrizio, John Murrough Golden

Articles

The model developed in (Fabrizio in J. Eng. Math., 2023) and (Fabrizio in Int. J. Eng. Sci. 44:529–539, 2006), involving the use of a local Reynolds number, is applied to describe phase transitions in a fluid. Specifically, it is applied in a magnetohydrodynamics context to study the evolution of turbulence in certain phenomena. The relevant equations describing the system are those of Navier-Stokes, Ginzburg-Landau and the magnetohydrodynamic equations, all suitably interconnected.

Entrepreneurial Competencies In Action: Online Fundraising Initiatives By University Students, Thomas M. Cooney, Martina Brophy

Articles

It has been argued that entrepreneurship educators are inclined to let students learn in a safe controlled environment, with no pressure except to pass the module. Students working in groups of three were given 12 weeks (Target 1) to develop a fundraising initiative, work with various stakeholders, and execute their online fundraising initiative to meet a target goal of €2000 (Target 2) per group. Employing approaches such as Effectuation, Lean Start-Up and the Business Model Canvas, a self-directed learning approach ensured students were able to take ownership of their learning journey with the lecturer acting as coach or facilitator. The …

On The Modelling Of Short And Intermediate Water Waves, Rossen Ivanov

Articles

Most of the model equations for water waves are approximations for the long-wave propagation regimes, since most of the energy of the wave motion is concentrated in these waves. Long waves (or shallow-water waves) are defined usually as the depth to wavelength ratio δ = h/λ < 0.05. Several famous integrable nonlinear equations, like the K d V equation [1,2], are models for long waves of small amplitude. The short waves (or waves over deep water) are usually defined with δ > 0.5, and the intermediate waves (or transitional waves) - with 0.05 < δ < 0.5. The intermediate and short waves received a lot less attention, and one reason is perhaps the fact that the corresponding approximations lead to more complicated, nonlinear and nonlocal equations. In [3] an integral equation for surface waves has been proposed for arbitrary wavelengths and finite depth. The problem has been studied in [4] and model equations both for long and short waves are derived from the governing equations as well. The short-wave effects usually compete with the capillarity effects and then resonances can be observed — these have been studied quite a lot, see for example [5–12]. For the intermediate long waves or for waves on deep water the so-called Benjamin–Ono (BO) [13–15] and the Intermediate Long Wave Equation (ILWE) [16–18] are derived for the internal waves below a flat surface, which leads to some simplifications and these models are in fact integrable.

The Lagrangian Formulation For Wave Motion With A Shear Current And Surface Tension, Conor Curtin, Rossen Ivanov

Articles

The Lagrangian formulation for the irrotational wave motion is straightforward and follows from a Lagrangian functional which is the difference between the kinetic and the potential energy of the system. In the case of fluid with constant vorticity, which arises for example when a shear current is present, the separation of the energy into kinetic and potential is not at all obvious and neither is the Lagrangian formulation of the problem. Nevertheless, we use the known Hamiltonian formulation of the problem in this case to obtain the Lagrangian density function, and utilising the Euler-Lagrange equations we proceed to derive some …

Triplet Sensitization Enables Bidirectional Isomerization Of Diazocine With 130 Nm Redshift In Excitation Wavelengths, Jussi Isokuortti, Thomas Griebenow, Jan-Simon Von Glasenapp, Tim Raeker, Timo Laaksonen, Rainer Herges, Nikita A. Durandin

Articles

Diazocines are bridged azobenzenes with phenyl rings connected by a CH2–CH2 group. Despite this rather small structural difference, diazocine exhibits improved properties over azobenzene as a photoswitch and most importantly, its Z configuration is more stable than the E isomer. Herein, we reveal yet another unique feature of this emerging class of photoswitches. In striking contrast to azobenzenes and other photochromes, diazocine can be selectively switched in E / Z direction and most intriguingly from its thermodynamically stable Z to metastable E isomer upon successive excitation of two different triplet sensitizers present in solution at the same time. This approach …

Burdens Of Proof In Establishing Negligence: A Comparative Law And Economics Analysis, Francesco Parisi, Giampaolo Frezza

Articles

Inherent in any judicial system is the need to allocate the burden of proof on one party. Within the realm of negligence torts, that burden is traditionally placed on the plaintiff, meaning that the plaintiff must bring forth sufficient evidence to establish negligence by the defendant. In effect, this is a legal presumption of non-negligence in favor of the defendant. In some jurisdictions for specific torts, defendants are, instead, presumed negligent, therefore requiring defendants to come forth with sufficient evidence to prove their due diligence. In this paper, we discuss the legal origins and effects of these differences in a …

The Public Administration Of Justice, Nicholas Bednar

Articles

Adjudicatory agencies decide who receives social-welfare benefits, which inventions deserve patents, and which noncitizens get to remain in the United States. Scholars have argued that agency adjudication lacks sufficient structural and procedural protections to ensure unbiased decision-making. Yet these critiques miss a key problem with agency adjudication: the lack of adjudicatory capacity. This Article argues that low-capacity agencies cannot satisfy the Due Process Clause's demand for accurate decision-making. To produce accurate decisions, adjudicatory agencies need sufficient levels of capacity: (1) material resources, (2) expert adjudicators, and (3) support staff When agencies lack these resources, their adjudicators rely on various coping …

Platinum Nanoparticles Inhibit Intracellular Ros Generation And Protect Against Cold Atmospheric Plasma-Induced Cytotoxicity, Sebnem Gunes, Zhonglei He, David Van Acken, Renee Malone, Patrick Cullen, James Curtin

Articles

Platinum nanoparticles (PtNPs) have been investigated for their antioxidant abilities in a range of biological and other applications. The ability to reduce off-target cold atmospheric plasma (CAP) cytotoxicity would be useful in Plasma Medicine; however, little has been published to date about the ability of PtNPs to reduce or inhibit the effects of CAP. Here we investigate whether PtNPs can protect against CAP-induced cytotoxicity in cancerous and non-cancerous cell lines. PtNPs were shown to dramatically reduce intracellular reactive species (RONS) production in U-251 MG cells. However, RONS generation was unaffected by PtNPs in medium without cells. PtNPs protect …
