Generation of unstructured grids and Euler solutions for complex geometries

Algorithms are described for the generation and adaptation of unstructured grids in two and three dimensions, as well as Euler solvers for unstructured grids. The main purpose is to demonstrate how unstructured grids may be employed advantageously for the economic simulation of both geometrically as well as physically complex flow fields

Prevalence of exclusive breastfeeding and its determinants in first 6 months of life: A prospective study

Background: Exclusive breastfeeding for first 6 months of life is recommended under Infant and Young Child Feeding practices in India. The objective of present study was to estimate the prevalence of exclusive breastfeeding during first 6 months of life of babies and to identify factors that interfere with the practice in the study area. Methods: A prospective cohort of 462 women who delivered at maternity unit of Government Medical College & Hospital, Rajkot, which is a tertiary care centre for the district, was studied. Data collection was done at hospital as well as during home visits of babies at 1, 3 and 6 months. Factors related to cessation of breastfeeding were analyzed using univariate, bivariate and multivariate analysis. Results: All 462 mothers reported breastfeeding their newborns. Prevalence of exclusive breastfeeding reported at 3 months was 97% which declined to 62% by 6 months of age of infants. Bivariate analysis revealed no significant association between interruption of exclusive breastfeeding before 6 months of age and various demographic, socioeconomic, maternal and infant characteristics. Multivariate analysis by logistic regression demonstrated no association between discontinuation of exclusive breastfeeding and socioeconomic status, maternal education and maternal age, number of antenatal visits, maternal employment and initiation of breastfeeding after delivery. Conclusion: Exclusive breastfeeding prevalence rate found higher than at national level indicating better feeding practices in these part of India. Also, factors classically considered as supportive for breastfeeding had shown no association with breastfeeding pattern in present study

The Volume of 2D Black Holes

It is shown that the definition for the volume of stationary black holes advocated in hep-th/0508108 readily generalizes to the case of dilaton gravity in D=2. The dilaton field is included as part of the measure. A feature observed in D=3 and 4 has been the impossibility to obtain infinite volume while retaining finite area without encountering some kind of pathology. It is demonstrated that this also holds in D=2. Consistency with spherically reduced gravity is shown. For the Witten black hole it is found that the area is proportional to the volume.Comment: 9 pages, 3 figures, uses iopart_mod.cl

Creditors Strike Back: The Return of the Cooperation Agreement

In the low interest rate environment that followed the Great Recession, a fanatical demand for high-yield investments provided private equity firms an opportunity. Newfound borrower leverage facilitated credit documents with few creditor safeguards and various loopholes. Borrowers subject to these “sponsor-favorable” terms now had options in times of financial distress. More specifically, they had the option to strike first. Utilization of coercive exchanges began in earnest around 2015 and has since flourished. Unmonitored portfolio companies experiencing financial distress now regularly rely on questionable interpretations of ambiguous contractual provisions to surreptitiously move assets away from creditors’ collateral baskets and subordinate lenders. These unprecedented acts of financial war are pure, self-interested behavior designed to seize and redistribute value. Creditors in this multiplayer prisoner’s dilemma have two choices: (i) cooperate with its creditor group and attempt to prevail by securing a majority coalition, or (ii) defect and work with the borrower who promises to share some of the spoils of victory. Scholars have thoroughly detailed private equity’s plan of attack. But what is missing is an exploration of creditor countermeasures to these new coercive exchanges. This Essay attempts to conceptualize the decision to coordinate and analyze the benefits and costs of cooperation. Further, this Essay explores the prevalent terms and basic design of cooperation agreements based on my unique review of a number of private disputes. The possibility of opportunistic behavior casts a long shadow in these battles of financial titans. The benefits of a coordinated response are clear, but there still exist many obstacles, including threats of free riding. And borrowers have myriad weapons in their arsenal to splinter adversary groups. In choosing between cooperation and defection, creditors know there may be no honor among thieves. “The first principle of Economics is that every agent is actuated only by self-interest. [But invariably an agent must choose to act] without, or with, the consent of others affected by his actions. In [a] wide sense[], the first species of actions may be called war; the second contract.

The New Mass Torts Bargain

Mass torts create a unique scale of harm and liabilities. Corporate tortfeasors are desperate to settle claims but condition settlement on the resolution of substantially all claims at a known price—commonly referred to as a global settlement. Without this, corporate tortfeasors are willing to continue with protracted and fragmented litigation across jurisdictions. Global settlements can be elusive in these cases. Mass torts are oftentimes characterized by heterogeneous victim groups that include both current victims and future victims—individuals whose harm has not yet manifested and may not do so for years. Despite this incongruence, future-victim claims must be aggregated as part of any global settlement. This is the tragedy of the mass tort anticommons: without unanimity, victim groups are unable to access settlement resources in a timely or meaningful way, but actual coordination across the group can be impossible. Current resolution structures have proven ill-equipped to address the novel challenges posed by mass torts. Many cases cannot satisfy Federal Rule of Civil Procedure 23’s (“Rule 23”) requirements for class action certification because of too many individual issues surrounding causation and damages. Multidistrict litigation (MDL) is the most frequently invoked resolution structure, but the MDL process has infirmities. MDL lacks many of Rule 23’s fundamental safeguards that protect process integrity and victim autonomy. MDL has become a captive settlement process. In response, a new strategy for resolving modern mass torts has emerged. Corporate defendants—including 3M, Johnson & Johnson, and Purdue Pharma—have turned to bankruptcy. These mass restructurings automatically halt the affected MDL cases and transfer proceedings to a bankruptcy court, a process I describe as “bankruptcy preemption.” Unfortunately, bankruptcy preemption replaces one deficient structure with another. Mass restructuring debtors are exploiting statutory gaps in the U.S. Bankruptcy Code in order to bind victims through an unpredictable, ad hoc structure. The new bargain creates myriad risks, including insolvent settlement trusts and disparate treatment across victim classes. This Essay is the first to attempt a reconceptualization of how modern mass torts should be resolved and delivers an unprecedented normative construct focused on addressing anticommons dynamics through statutory amendments to the Bankruptcy Code. These changes, coupled with an evolved perspective on fundamental structural anomalies, are designed to improve predictability, efficiency, and victim recoveries

Scarlet-Lettered Bankruptcy: A Public Benefit Proposal for Mass Tort Villains

Financially distressed companies often seek refuge in federal bankruptcy court to auction valuable assets and pay creditor claims. Mass tort defendants—including 3M, Johnson & Johnson, and Purdue Pharma—introduce new complexities to customary Chapter 11 dynamics. Many mass tort defendants engage in malfeasance that inflicts widespread harm. These debtors fuel public scorn and earn a scarlet letter that can destroy value for an otherwise profitable business. Scarlet-lettered companies could file for bankruptcy and quickly sell their assets to fund victims’ settlement trusts. This Article argues, however, that this traditional resolution option would eviscerate victim recoveries. Harsh public scrutiny has diminished the value of the resources necessary to satisfy claims, creating a discount that must be borne by victims. My public benefit proposal charts a new course. Instead of accepting fire-sale prices and an underfunded settlement trust, the scarlet-lettered company emerges from bankruptcy as a corporation for the public benefit. This modified reorganization offers victims the greatest recovery. The continued operation preserves value during a transition period, after which the going concern can be sold efficiently. Assets that have been tainted by tortious conduct are cleansed behind a philanthropy shield and then sold to capture the value rebound. The victims’ collective is the owner of the new company and can participate in a shareholder windfall if there is strong postbankruptcy performance. At the forefront of a new trend in aggregate litigation, this Article proposes a public benefit alternative to traditional resolution mechanisms. This approach delivers utility that will support application in a variety of contexts, assuming certain governance safeguards are maintained. In our new age of greater personal and corporate accountability, more scarlet-lettered companies will emerge and ultimately land in bankruptcy. The need to address the disposition of tainted assets will be paramount in compensating mass tort victims trying to reassemble fractured pieces. This Article explains a new phenomenon and reconceptualizes resolution dynamics in a way that will have policy implications that transcend aggregate litigation
