Soil Gas Investigation of Porter Ranch, Related to Aliso Canyon Gas Storage Field
No full textAliso Canyon gas storage facility is located in the Santa Susana Mountains, California. The facility is depleted oil field, re-purposed for gas storage in 1973. Porter Ranch is a residential community, adjacently located to the south of the facility. On October 23, 2015, a blowout was discovered at well SS-25. Several residential families have been relocated due to concerns of health risk due to poor air quality. On February 18, 2016, California state officials announced the leak was sealed. There is a significant public interest concerning the safety of this facility. Our investigation is to measure soil gasses in Porter Ranch, determine if stored gasses have migrated out of the storage field, and released through the soil into the atmosphere. Detected gasses will be characterized to determine biogenic, native thermogenic, or non-native thermogenic source. Our methods to survey soil gasses are the installation of soil gas wells, and testing of soil gasses. These wells will be located in Porter Ranch. Wells will be monitored weekly or as needed and methane values tested with a photoionization detector (PID)
Geology, Structure, and Detrital Zircon Geochronology of Central Blue Ridge, San Gabriel Mountains, California
No full textThe Blue Ridge schist body is a member of the larger widely distributed group of schist bodies known as the Pelona-Orocopia-Rand schists (POR). Blue Ridge and the other schists are generally thought to be composed of marine trench protoliths that were underplated beneath North America during flat slab subduction of the Farallon Plate. Mount Pinos, Sierra Pelona, Blue Ridge, and Orocopia Mountains schist bodies are generally accepted to have once been connected prior to dissection and offset along the San Andreas transform boundary. Although these schist bodies have been studied at various levels, Blue Ridge has received relatively little attention in terms of lihologic, structural, and geochronologic work. Subunits on Blue Ridge appear to be complexly interleaved or interbedded, contrasting with some previous interpretations that metabasites should exist in the basal portions, followed by metacherts, calc-silicates, and quartzofeldspathic schist in the upper portions (i.e. an intact sequence of oceanic plate overlain by calcareous and siliceous muds followed by turbidites or sandstones). Detailed mapping shows that these subunits are randomly distributed throughout the structural sections of the schist body. Even at basal to mid structural levels, quartzofeldspathic schist is ubiquitous, and interleaved or interbedded with all other subunits. Despite extensive analysis, there does not appear to be evidence qualitatively, for a systematic up-section variation in metamorphic grade. According to analyses of 56 thin sections, the majority of central Blue Ridge schist subunits were metamorphosed at lowermost amphibolite facies, or at the boundary between greenschist and amphibolite facies. This is consistent with published results on metamorphic grade of Blue Ridge. A subset of syn-metamorphic asymmetric folds in two locations appears to record shearing concomitant with subduction and extrusion of the schist body. One locality records top-to-SW and top-to-NE sense of shear, and a second locality records only top-to SW sense of shear after vertical axis rotations are performed. The resulting orientation restores to that of the convergence vector of the Farallon plate during the late Cretaceous if the Blue Ridge block is back rotated approximately 40–45 degrees. Additionally, two sets of map-scale folds exist in the study area. 1) A syn-metamorphic tight folding event with northerly trending fold hinges demonstrates that the maximum principal stress direction associated with syn-metamorphic folding varies from N78E-S78W to N73W-S73E before vertical-axis rotation. 2) A younger post-metamorphic open group of folds with WNW trending fold axes demonstrates that the maximum principal stress direction associated with the formation of these folds was N29E-S29W before vertical axis rotation. U-Pb geochronology results indicate that the Blue Ridge schist may be treated as a quasi-intact sedimentary sequence. Two independent structural sections at near basal to mid structural levels, show that the schist body appears to preserve an intact proto-stratigraphy that displays a younging trend up-section. Combined maximum depositional ages, indicated by youngest single grain (YSG) analysis, range from 88.3 ± 2.6 Ma to 75.6 ± 1.2 Ma (2σ uncertainty) up-section. Age vs. depth relations for the structural sections show remarkable congruence between the YSG's per sample and relative depth measurements, possibly due to extreme tectonic flattening of the schist. These results potentially allow for the analysis of detrital zircon provenance changes up-section through time.Detrital zircon analysis shows that the Blue Ridge schist body is most similar in provenance signature to the Sierra Pelona schist body, followed closely by the Mount Pinos schist body, lending further support for the proposed connection of the three schist bodies in the past. In contrast, the Orocopia Mountains schist body is sufficiently different in provenance signature from the Blue Ridge, Sierra Pelona, and Mount Pinos schist bodies, to call into question a contiguous origin or similar depocenter between them. Blue Ridge detrital zircon samples also appear to record the expected shifts in provenance occurring up-section through time that reflect the progressive evolution from outboard to inboard source detritus (i.e. the breaching of the Sierran-Peninsular Ranges Arc and allowance of detritus from the Mojave block and San Gabriel terrane to reach the continental margin) seen in forearc strata and pooled zircon data from the POR schists. In general, the sections show the progression of erosional detritus from dominantly the Sierran-Peninsular Ranges Arc at basal structural levels (88.3 Ma), followed by the first appearance of inboard detritus in the mid structural levels (81.8 Ma), and culminating with the marked increase of inboard detritus at the uppermost structural level (75.6 Ma). Assuming that the other schist bodies also preserve relatively intact quasi-stratigraphic sections, evaluation of published data sets from Mount Pinos and Sierra Pelona schist bodies show similar provenance development through time (if the samples are defined by the youngest single grain and are assumed to roughly represent the maximum depositional age of the structural level). It is acknowledged however, that this interpretation of the data relies on several assumptions that are based on the Blue Ridge sections, and that the data from Blue Ridge is limited in terms of the number of samples (7) as well as the low number of analyses per sample (24–72 grains). This study shows that marine trench protoliths of the Blue Ridge schist were deposited between 88.3 Ma and approximately 75.6 Ma (minimum), then deformed in a northeast-dipping subduction zone. Two generations of folds record syn-metamorphic Laramide subduction-related deformation, followed by a period of open folding that predated development of the San Gabriel-San Andreas transform fault system. The present-day orientation of fold hinges on Blue Ridge reflects counterclockwise block rotation of ~17 degrees during development of the restraining double bend in the San Andreas fault, and clockwise block rotation of ~40–45 degrees that may be the result of transrotation between the Punchbowl and San Andreas faults
Enhanced metastasis risk prediction in cutaneous squamous cell carcinoma using deep learning and computational histopathology
No full textCutaneous squamous cell carcinoma (cSCC) is the most common skin cancer with metastatic potential and development of metastases carries a poor prognosis. To address the need for reliable risk stratification, we developed cSCCNet, a deep learning model using digital pathology of primary cSCC to predict metastatic risk. A retrospective cohort of 227 primary cSCC from four centres is used for model development. cSCCNet automatically selects the tumour area in standard histopathological slides and then stratifies primary cSCC into high- vs. low-risk categories, with heatmaps indicating most predictive tiles contributing to explainability. On a 20% hold-out testing cohort, cSCCNet achieves an area under the curve (AUC) of 0.95 and 95% accuracy in predicting risk of metastasis, outperforming gene expression-based tools and clinicopathologic classifications. Multivariate analysis including common clinicopathologic classifications confirm cSCCNet as an independent predictor for metastasis, implying it identifies predictive factors beyond known clinicopathologic risk factors. Histopathological analysis including multiplex immunohistochemistry suggests that tumour differentiation, acantholysis, desmoplasia, and the spatial localisation of lymphocytes relative to tumour tissue may be important in predicting risk of developing metastasis. Although further validation including prospective evaluation is required, cSCCNet has potential as a reliable and accurate tool for metastatic risk prediction that could be easily integrated into existing histopathology workflows
Two Kinds of Plain Meaning
No full textIs plain meaning so plain? This is not meant to be a philosophical question, but one deserving serious legal analysis. The plain-meaning rule claims to provide certainty and narrow statutes\u27 domains. The author agrees with, as a relative claim, comparing plain meaning with purposivism. She does not agree that plain-meaning analysis is as easy as its proponents suggest. In this piece, the author teases out two very different ideas of plain meaning--ordinary/popular meaning and expansive/legalist meaning--suggesting that doctrinal analysis requires more than plain-meaning simpliciter. Perhaps more importantly, she argues that plain meaning, as legalist meaning, can quite easily expand a statute\u27s scope, relative to a baseline of ordinary meaning or the status quo ex ante
Making Constitutional Doctrine in a Realist Age
No full textIn this article the author considers three examples of modern constitutional doctrine that show how judges have stolen bits and pieces from popularized skepticisms about the job of judging and have molded this stolen rhetoric into doctrine. In the first example, she asks whether constitutional law\u27s recent penchant for doctrinal rules based on clear law could have existed without the modern age\u27s obsession with legal uncertainty. In the second, the author considers whether our contemporary rhetoric of constitutional interests and expectations reflects modern critiques of doctrine as failing to address social needs. In the third, she asks how an offhand reference to the term fundamental could come to describe a legal category defined by courts\u27 own fears of illegitimacy except in an age self-conscious of the judiciary\u27s institutional weaknesses. If the author is right about these examples, it may be that what was once said of modern painting\u27s abstraction--that whatever else it was about, it was about painting --is true of modern doctrine\u27s abstraction as well: that it is about doctrine and doctrine\u27s struggle in an age self-conscious of the possibility of doctrinal failure

Decision Theory and \u3ci\u3eBabbitt v. Sweet Home\u3c/i\u3e: Skepticism About Norms, Discretion, and the Virtues of Purposivism
No full textIn this writing, the author applies a “decision theory” of statutory interpretation, elaborated recently in the Yale Law Journal, to Professor William Eskridge’s illustrative case, Babbitt v. Sweet Home Chapter of Communities for a Great Oregon. In the course of this application, she takes issue with the conventional wisdom that purposivism, as a method of statutory interpretation, is inevitably a more virtuous model of statutory interpretation. First, the author questions whether we have a clear enough jurisprudential picture both of judicial discretion and legal as opposed to political normativity. Second, she argues that, under decision theory, Sweet Home is a far easier case than either Justice Stevens’s or Justice Scalia’s opinions reveal. Finally, the author critiques both opinions for failing to rely on norms borrowed from Congress’s actual decisions in the 1982 Endangered Species Act Amendments. The question then, is not “norms or not,” but whose norms, Congress’s or the courts’, should apply
Self-Defense and Subjectivity
No full textThe law of self-defense has rarely produced as much academic or popular heat as it has in the past two decades. Widely publicized trials, such as the Goetz and Menendez cases, have generated deep-seated fears of a law unmoored from principle. Those fears have generated a standard public critique--that the criminal law has become too soft and subjective, too wedded to syndrome science and prone to weak-kneed affection for defendants. The criminal law has lost its objectivity, so the argument goes. The poster child, and even the alleged cause of this development, is the battered woman.
In this article, the author presents evidence that much of this public debate is misdirected: the charge of subjectivity and abuse, if not a deception, is a diversion. The problem with the law of self-defense is neither new nor limited to the battered woman; it is as old and as persistent as the law\u27s search for an objective meaning for necessity. Based on a survey of twenty years of self-defense cases, the author sought to test claims of objectivity by focusing on what purports to be one of the most objective of self-defense rules: the requirement that the threat must have been imminent for the defendant\u27s response to have been permissible. Time is not something legal scholars generally study. The author chose to study imminence, however, because it seems the quintessential definition of objectivity, the hard case. Perhaps more importantly, there is no more controversial element in the law of self-defense. As George Fletcher has put it: The central debate in the theory of self-defense for the last decade has been whether we should maintain a strict requirement of imminence.
Part I of this article explains the legal issues of imminence and the law of self-defense as well as the construction of the legal debate as a question of subjectivity. Part II presents the results of the author’s survey and its method. Part III argues that the so-called objectivity of contemporary doctrine is belied by its content; that doctrine we call objective leaves open many questions and risks the embrace of contradictions. This Part traces these failures to a basic theoretical disagreement about the meaning of necessity in the law of self-defense. Part IV argues that subjectivity cannot resolve these questions. It argues that even the apparently most subjective aspects of self-defense law--such as battered woman syndrome--may rest on objective legal propositions. Finally, Part V questions whether a discourse of objectivity and subjectivity really helps us understand the criminal law, in self-defense or the many other places it may be found. The author argues that if there is a problem with the law of criminal defenses today, it is not with syndromes or subjectivity, but with a criminal law that purports to be neutral and precise but remains full of contested meanings
The Constitution and Legislative History
No full textIn this article, the author provides an extended analysis of the constitutional claims against legislative history, arguing that, under textualists’ own preference for constitutional text, the use of legislative history should be constitutional to the extent it is supported by Congress’s rulemaking power, a constitutionally enumerated power.
This article has five parts. In part I, the author explains the importance of this question, considering the vast range of cases to which this claim of unconstitutionality could possibly apply—after all, statutory interpretation cases are the vast bulk of the work of the federal courts. She also explains why these claims should be of greater concern to a variety of constitutional theorists, particularly those who embrace theories of popular and common law constitutionalism, but as well to originalists.
In part II, the author considers the textualist arguments against the constitutionality of legislative history. Article I, Section 7 provides that any bill must pass the House and the Senate and be presented to the President for veto or signature. As a number of textualists have argued, legislative history is not passed by both houses or signed by the President. Call this the “bicameralism argument.” Her answer to the bicameralism argument lies in a constitutional text that statutory textualists seem to have forgotten: Article I, Section 5 gives explicit power to Congress to set its own procedures, a power that gives legitimacy to legislative history created pursuant to those procedures. In fact, new developments in statutory interpretation theory (decision process theory) suggest that, in some cases, the only way to resolve textual conflict is to consider legislative procedure.
In part III, the author considers a second prominent argument against the constitutionality of legislative history: non-delegation. Critics argue that Congress may not delegate the “legislative power” granted under the Constitution to members or committees, as only the entire Congress may constitutionally exercise that power. Call this the “non-delegation” argument. Again, her response is based on constitutional text: Article I, Section 5 specifically sanctions delegation to less than the whole of Congress; more importantly, there is no general norm against self-delegation stated explicitly or even implicitly in the Constitution. Finally, the author suggests that there is a certain inconsistency in the assertion of these claims: the non-self-delegation and bicameralism arguments can both be used to indict canons of construction, which textualists offer as the leading alternative to legislative history, but which have no supporting text comparable to Article I section 5 in the Constitution.
In part IV, she considers arguments that judges’ use of legislative history violates the separation of powers because it allows the legislature to exceed the bounds of the “judicial power.” This argument can rather easily be turned on its head: in the quotations offered at the beginning of this article, members of Congress argue that judges are exercising the “legislative power” when they rewrite statutes without considering legislative history. As has been argued at length elsewhere, the use of “adjectival” argument in structural controversies—relying upon the terms “legislative, executive, and judicial”—perpetuates a weak understanding of the separation of powers, and one that the Constitution’s own text belies. The separation of powers does not prevent recourse to legislative history; in fact, as the article explains, blindness to legislative history may create different kinds of structural risks—risks to federalism, rather than risks to the separation of powers.
Finally, in part V, the author concludes by suggesting that we should retire the strong form of the legislative history unconstitutionality argument, by which she means the claim that the constitution bars any and all legislative history. Instead, we should far more actively interrogate serious questions about the use of legislative history in particular cases. Can it really be wise—or even constitutional—for a judge to impose a meaning on an ambiguous statute with reference to the state-ments of a filibustering minority, or privilege some texts in ways that violate Congress’s rules? Fidelity to Congress, and the importance of Congress’s constitutional rules—what Francis Lieber once called the “common law” of the Congress—has yet to be theorized within this more pressing, but particular, sphere
