Electrochemically-Assisted Low Power Density Laser Writing On Stainless Steel Via Enrichment Of Chromium Oxides, Zechariah J. Pfaffenberger, Lianlian Liu, Tae Kyong John Kim, Vignesh Venkataramani, Lydia Kisley

Faculty Scholarship

Laser color marking produces nearly permanent, environmentally friendly, vibrant colors on surfaces. However, previous work has used high-power-density pulsed lasers to induce the physicochemical reactions for marking. Here, laser color marking on stainless steel 304 (SS304) is performed with a less expensive continuous wave (CW) laser and a power density five orders of magnitude below that previously reported by combining an electrochemical cell with a fluorescence microscope. Using a combination of optical microscopy, x-ray photoelectron spectroscopy, and bulk electrochemistry, it is demonstrated that the laser-induced luminescence and colors are due to enrichment (32 ± 9% increase) of Cr₂O₃ in the …

A Toda Bracket Convergence Theorem For Multiplicative Spectral Sequences, Eva Belmont

Faculty Scholarship

Moss’ theorem, which relates Massey products in the -page of the classical Adams spectral sequence to Toda brackets of homotopy groups, is one of the main tools for calculating Adams differentials. Working in an arbitrary symmetric monoidal stable simplicial model category, we prove a general version of Moss’ theorem which applies to spectral sequences that arise from filtrations compatible with the monoidal structure. This involves the study of Massey products and Toda brackets in a non-strictly associative context. The theorem has broad applications, e.g., to the computation of the motivic slice spectral sequence and other colocalization towers.

Bound: The Imaginative Surplus Of Contractual Intent, Elizabeth F. Emens

Faculty Scholarship

Contract law is generally understood in terms of enforcement. The legal definition of a contract is a promise that the state will enforce. Individuals are empowered by contract law to create legal arrangements that the state will step in and enforce. And yet most contracts never make it to court.

This Article inverts the conventional focus on enforcement through a study of extralegal contracts. These are formal written agreements that parties call contracts but are not intended for legal enforcement. Examples of these extralegal contracts include no-suicide contracts and contracts for sexual slavery.

Examining extralegal contracts offers multiple insights. First, …

Tort Law Heterodoxy In China, Benjamin L. Liebman, Rachel E. Stern, Eva Wenwa Gao, Xiaohan Wu

Faculty Scholarship

Chinese courts routinely ask defendants to pay damages without evidence of negligence while relying on concepts such as fairness, substantive justice, or discretion. This chapter examines how Chinese courts arrive at decisions that feel fair or just in cases where they refer to those ideas. Analysis of a dataset of 10,000 judicial decisions in personal injury cases suggests that Chinese courts refer to these concepts when they impose liability on two types of parties: (1) participants in a shared activity and (2) those who control a physical space. By assigning legal responsibility in these cases, Chinese courts acknowledge traumatic harm, …

Functionalizing Polyethersulfone Membranes: Using Nmr To Avoid Pitfalls When Using Uv-Induced Polymerization To 'Graft From' Surfaces, Priyanka Suresh, Megan M. Sibley, Amy C. Che, Christine E. Duval

Faculty Scholarship

For nearly 30 years, UV-induced free radical polymerization has been used to modify the surface chemistry of polyethersulfone (PES) membranes, films, and coatings. The initial mechanism for the grafting process was introduced in the 1990s and supported without direct evidence of covalent bond formation. Since then, claims of ‘grafting from’ membranes in the literature rely on similar evidence using a combination of gravimetry, attenuated total reflectance infrared spectroscopy, contact angle goniometry, water sorption, and/or water permeance. While these techniques provide evidence of the presence of a polymer coating, they do not provide direct evidence of covalent bond formation between the …

Effect Of Anesthesia And Diurnal Variation On Chronic Vagus Nerve Activity In Rats, Bhanu P. Kotamraju, Grant A. Mccallum, Dominique M. Durand

Faculty Scholarship

The vagus nerve, serving as a pivotal link between the brain and vital organs, regulates crucial physiological functions. It plays a central role in maintaining homeostasis within the body and must dynamically adapt to changing conditions such as anesthesia or sleep. While vagal tone, typically estimated indirectly from heart rate variability, has been extensively studied, direct measurement of vagal activity during sleep and anesthesia remains unreported to date. Recent technological advancements have facilitated the recording of vagus nerve activity in freely moving rodents using small, highly flexible carbon nanotube yarns. Consequently, it is now feasible to directly investigate vagal activity …

Cgas/Sting-Independent Induction Of Type I Interferon By Inhibitors Of The Histone Methylase Kdm5b, Monica M. Montano, I. Ju Yeh, Wannarasmi Ketchart

Faculty Scholarship

Studies support the role of hexamethylene bis-acetamide [HMBA] induced protein 1 (HEXIM1) as a tumor suppressor. We previously reported that the histone demethylase, KDM5B, inhibits the expression of HEXIM1, and KDM5B inhibitors (KDM5Bi) upregulate HEXIM1 expression. As a consequence, KDM5Bi inhibited cell proliferation, induced differentiation, potentiated sensitivity to cancer chemotherapy, and inhibited breast tumor metastasis. HEXIM1 is crucial for the regulation of triple-negative breast cancer (TNBC) phenotype by KDM5Bi. Type I Interferon (IFN-I) employs the immune system in the tumor microenvironment to restrict tumor growth. Moreover, therapeutic approaches (including mainstay chemotherapy) engage IFN-I signaling. We report herein that HEXIM1 and …
