Annual Survey of Virginia Law: Criminal Law and Procedure
This article discusses holdings and trends in the published cases of the Virginia Court of Appeals and the Supreme Court of Virginia from August 1996 to July 1997. Although the form of this article generally follows the same form used by prior authors, several subject headings have been renamed to reflect the current focus of the courts. For example, during this period the court of appeals grappled with the community caretaker doctrine, bifurcated sentencing proceedings in felony cases, jury selection, and various hearsay exceptions. The supreme court addressed an indigent defendant\u27s right to expert assistance, administrative license suspensions, and speedy trial issues

Phonotactics, graphotactics and contrast:The history of Scots dental fricative spellings
The spelling conventions for dental fricatives in Anglic languages (Scots and English) have a rich and complex history. However, the various – often competing – graphemic representations (<þ>, <ð>, <y> and <th>, among others) eventually settled on one digraph, <th>, for all contemporary varieties, irrespective of the phonemic distinction between /ð/ and /θ/. This single representation is odd among the languages’ fricatives, which tend to use contrasting graphemes (cf. <f> vs <v> and <s> vs <z>) to represent contrastive voicing, a sound pattern that emerged nearly a millennium ago. Close examinations of the scribal practices for English in the late medieval period, however, have shown that northern texts had begun to develop precisely this type of distinction for dental fricatives as well. Here /ð/ was predominantly represented by <y> and /θ/ by <th> (Jordan 1925; Benskin 1982). In the late fifteenth and early sixteenth centuries, this ‘Northern System’ collapsed, due to the northward spread of a London-based convention using exclusively <th> (Stenroos 2004). This article uses a rich body of corpus evidence for fifteenth-century Scots to show that, north of the North, the phonemic distinction was more clearly mirrored by spelling conventions than in any contemporary variety of English. Indeed, our data for Older Scots local documents (1375–1500) show a pattern where <y> progressively spreads into voiced contexts, while <th> recedes into voiceless ones. This system is traced back to the Old English positional preferences for <þ> and <ð> via subsequent changes in phonology, graphemic repertoire and letter shapes. An independent medieval Scots spelling norm is seen to emerge as part of a developing, proto-standard orthographic system, only to be cut short in the sixteenth century by top-down anglicisation processes
Automatically generating adaptive logic to balance non-functional tradeoffs during reconfiguration
Increasingly, high-assurance software systems apply selfreconfiguration in order to satisfy changing functional and non-functional requirements. Most self-reconfiguration approaches identify a target system configuration to provide the desired system behavior, then apply a series of reconfiguration instructions to reach the desired target configuration. Collectively, these reconfiguration instructions define an adaptation path. Although multiple satisfying adaptation paths may exist, most self-reconfiguration approaches select adaptation paths based on a single criterion, such as minimizing reconfiguration cost. However, different adaptation paths may represent tradeoffs between reconfiguration costs and other criteria, such as performance and reliability. This paper introduces an evolutionary computationbased approach to automatically evolve adaptation paths that safely transition an executing system from its current configuration to its desired target configuration, while balancing tradeoffs between functional and non-functional requirements. The proposed approach can be applied both at design time to generate suites of adaptation paths, as well as at run time to evolve safe adaptation paths to handle changing system and environmental conditions. We demonstrate the effectiveness of this approach by applying it to the dynamic reconfiguration of a collection of remote data mirrors, with the goal of minimizing reconfiguration costs while maximizing reconfiguration performance and reliability

Characterization of the fecal microbiome in cats with inflammatory bowel disease or alimentary small cell lymphoma.
Feline chronic enteropathy (CE) is a common gastrointestinal disorder in cats and mainly comprises inflammatory bowel disease (IBD) and small cell lymphoma (SCL). Both IBD and SCL in cats share features with chronic enteropathies such as IBD and monomorphic epitheliotropic intestinal T-cell lymphoma in humans. The aim of this study was to characterize the fecal microbiome of 38 healthy cats and 27 cats with CE (13 cats with IBD and 14 cats with SCL). Alpha diversity indices were significantly decreased in cats with CE (OTU p = 0.003, Shannon Index p = 0.008, Phylogenetic Diversity p = 0.019). ANOSIM showed a significant difference in bacterial communities, albeit with a small effect size (P = 0.023, R = 0.073). Univariate analysis and LEfSE showed a lower abundance of facultative anaerobic taxa of the phyla Firmicutes (families Ruminococcaceae and Turicibacteraceae), Actinobacteria (genus Bifidobacterium) and Bacteroidetes (i.a. Bacteroides plebeius) in cats with CE. The facultative anaerobic taxa Enterobacteriaceae and Streptococcaceae were increased in cats with CE. No significant difference between the microbiome of cats with IBD and those with SCL was found. Cats with CE showed patterns of dysbiosis similar to those in found people with IBD
Charting the rise and demise of a phonotactically motivated change in Scots
Although Old English [f] and [v] are represented unambiguously in Older Scots orthography by <f> and <v> (or <u>) in initial and morpheme-internal position, in morpheme-final position <f> and <v>/<u> appear to be used interchangeably for both of these Old English sounds. As a result, there is often a mismatch between the spellings and the etymologically expected consonant. This paper explores these spellings using a substantial database of Older Scots texts, which have been grapho-phonologically parsed as part of the From Inglis to Scots (FITS) project. Three explanations are explored for this apparent mismatch: (1) it was a spelling-only change; (2) there was a near merger of /f/ and /v/ in Older Scots; (3) final [v] devoiced in (pre-)Older Scots but this has subsequently been reversed. A close analysis of the data suggests that the Old English phonotactic constraint against final voiced fricatives survived into the pre-Literary Scots period, leading to automatic devoicing of any fricative that appeared in word-final position (a version of Hypothesis 3), and this, interacting with final schwa loss, gave rise to the complex patterns of variation we see in the Older Scots data. Thus, the devoicing of [v] in final position was not just a phonetically natural sound change, but also one driven by a pre-existing phonotactic constraint in the language. This paper provides evidence for the active role of phonotactic constraints in the development of sound changes, suggesting that phonotactic constraints are not necessarily at the mercy of the changes which conflict with them, but can be involved in the direction of sound change themselves

Two-level system noise reduction for Microwave Kinetic Inductance Detectors
Noise performance is one of the most crucial aspects of any detector.
Superconducting Microwave Kinetic Inductance Detectors (MKIDs) have an "excess"
frequency noise that shows up as a small time dependent jitter of the resonance
frequency characterized by the frequency noise power spectrum measured in units
of Hz^2/Hz. Recent studies have shown that this noise almost certainly
originates from a surface layer of two-level system (TLS) defects on the
metallization or substrate. Fluctuation of these TLSs introduces noise in the
resonator due to coupling of the TLS electric dipole moments to the resonator's
electric field. Motivated by a semi-empirical quantitative theory of this noise
mechanism, we have designed and tested new resonator geometries in which the
high-field "capacitive" portion of the CPW resonator is replaced by an
interdigitated capacitor (IDC) structure with 10 - 20 micron electrode spacing,
as compared to the 2 micron spacing used for our more conventional CPW
resonators. Measurements show that this new IDC design has dramatically lower
TLS noise, currently by about a factor of ~29 in terms of the frequency noise
power spectrum, corresponding to an improvement of about a factor of 29^(1/2)
in NEP. These new devices are replacing the CPW resonators in our next design
iteration in progress for MKIDCam. Opportunities and prospects for future
reduction of the TLS noise will be discussed.Comment: 4 pages, 5 figures, Proceedings of the 13th International Workshop on
