Magnitude and regulation of zooplankton community production across boreal lakes
Authors: F. St‐Gelais Nicolas , Sastri Akash R. , del Giorgio Paul A. , Beisner Beatrix E.
Published: October 2017

A major outstanding question in plankton ecology is whether the regulation of zooplankton production at the community level follows the same patterns that have been observed for individual populations. We used a novel biochemical approach to estimate in situ rates of crustacean zooplankton community production in 83 boreal lakes, with the objective of identifying the main drivers of zooplankton production at the community level across the boreal landscape. Our results show that the relationship of zooplankton community production to average community body size, total biomass, and temperature is comparable to what has been observed for individual populations. At the community level, however, there are additional drivers, including lake morphometry, and catchment properties, which further influence zooplankton production and which cannot be inferred from population level patterns.

Published: October 2017

Introduction

The deep inferior epigastric perforator (DIEP) flap is one of the most commonly utilized flaps of reconstructive surgery. Although the horizontal flap design is the most commonly used, this flap can be vertically designed to avoid drawbacks such as excessive tissue dissection, relatively reduced flap perfusion, and scarification of the contralateral flap opportunity. The aim of this report is to present our case series for foot and ankle reconstruction with vertical designed DIEP flap.

Patients and methods

The free vertically designed DIEP flaps (VDIEP) were used in eight patients (7 male, 1 female) whose age is in a range of 20–66 years for soft tissue reconstructions in the ankle and foot region over a five‐year period. The range of defects’ size was from 8 × 5 cm to 15 × 7 cm and the causes were electrical burn, trauma and diabetic foot infections.

Results

Flap dimensions varied from 10 × 6 cm to 17 × 9 cm. All the flaps had two or more perforators, and all flaps survived completely. There were no early or late complications. We followed up the patients for 10 months in average. We observed no functional problems, especially in main motions of foot and ankle like eversion, inversion, flexion or extension except one patient. Donor site scars were acceptable in all patients.

Conclusions

The VDIEP flap may be an option for selected lower extremity soft tissue reconstructions, and it may be an alternative to classically designed abdominal flaps.
Ground state solutions for the nonlinear Schrödinger‐Poisson systems with sum of periodic and vanishing potentials
Authors: Xie Weihong , Chen Haibo , Shi Hongxia

We study the existence of ground state solutions for the following Schrödinger‐Poisson equations:

urn:x-wiley:mma:media:mma4602:mma4602-math-0001
where
is the sum of a periodic potential Vp and a localized potential Vloc and f satisfies the subcritical or critical growth. Although the Nehari‐type monotonicity assumption on f is not satisfied in the subcritical case, we obtain the existence of a ground state solution as a minimizer of the energy functional on Nehari manifold. Moreover, we show that the existence and nonexistence of ground state solutions are dependent on the sign of Vloc.
Rapid dual‐echo ramped hybrid encoding MR‐based attenuation correction (dRHE‐MRAC) for PET/MR
Authors: Jang Hyungseok , Liu Fang , Bradshaw Tyler , McMillan Alan B.
Published: October 2017

Purpose

In this study, we propose a rapid acquisition for MR‐based attenuation correction (MRAC) in positron emission tomography (PET)/MR imaging, in which an ultrashort echo time (UTE) image and an out‐of‐phase echo image are obtained within a single rapid scan (35 s) at high spatial resolution (1 mm3), which allows accurate estimation of a pseudo CT image using 4‐class tissue classification (discrete bone, discrete air, continuous fat, and continuous water).

Methods

In dual‐echo ramped hybrid encoding (dRHE), a UTE echo is directly followed by a second out‐of‐phase echo, in which hybrid spatial encoding combining single‐point imaging and 3‐dimensional radial frequency encoding is used to improve the quality of both images. Two‐point Dixon reconstruction is used to estimate fat‐ and water‐separated images, and UTE images are used to estimate bone. Air and bone segmentation is improved by using multiple UTE images with an advanced hybrid‐encoding scheme that allows reconstruction of multiple UTE images. To evaluate the proposed method, dRHE‐MRAC PET/MR brain imaging was performed in 10 subjects. Dice coefficients and PET reconstruction errors relative to CT‐based attenuation correction were compared with existing system MRAC approaches.

Results

In dRHE‐MRAC, the Dice coefficients for soft tissue, air, and bone were respectively 0.95 ± 0.01, 0.62 ± 0.06, and 0.78 ± 0.05, which was a significantly improved result compared with existing approaches. In most brain regions, dRHE‐MRAC showed significantly reduced PET error (less than 1%) with P values less than 0.05.

Conclusions

Dual‐echo ramped hybrid encoding enables rapid and robust imaging for MRAC with a very rapid acquisition. Magn Reson Med 79:2912–2922, 2018. © 2017 International Society for Magnetic Resonance in Medicine.
Correlation between the CAG repeat size and electrophysiological findings in patients with spinal and bulbar muscular atrophy
Authors: Kim Hyunjin , Lim Young‐Min , Lee Eun‐Jae , Oh Yeo Jin , Kim Kwang‐Kuk
Published: October 2017

Introduction

Spinal and bulbar muscular atrophy (SBMA) is caused by the expansion of a CAG repeat in the androgen receptor gene. The relationship between the CAG repeat size and electrophysiological findings is not completely understood.

Methods

We retrospectively analyzed 62 SBMA patients to assess the correlation between their CAG repeat size and electrophysiological findings.

Results

In multiple regression analysis including age at examination and disease duration, we identified a negative correlation between the CAG repeat size and the compound muscle action potential (CMAP) amplitude. No significant correlation was found between the CAG repeat size and sensory nerve action potential (SNAP) amplitude.

Discussion

Contrary to previous reports of motor‐ and sensory‐dominant phenotypes correlating with CAG repeat sizes, the CAG repeat size was negatively correlated only with CMAP amplitude, and not with SNAP amplitude. Muscle Nerve 57: 683–686, 2018
An analysis of mechanisms used by CSOs in the promotion of community participation in governance in Kenya
Authors: Munene Jane Wamaitha , Thakhathi D. Reckson
Published: October 2017

Civil society organizations (CSOs) are often perceived to provide the magic bullet to complex societal problems including alternative approaches that ensure good governance. Fresh new research is therefore needed due to the prevailing paradox of escalating governance challenges in Kenya despite CSOs efforts to address the same. This paper specifically seeks to understand mechanisms that CSOs use as they seek to intervene in governance issues in Kenya. It links persistent poor governance happening at the counties to inadequate mechanisms used by CSOs. It argues that CSOs have not been bold enough to confront poor governance but, instead, have used superficial mechanisms with little outcomes. They have particularly focused on providing trainings and creating awareness and have shied away from more direct engagement with poor governance such as monitoring utilization of public funds. The study methodology involved a survey, focus group discussions, and in‐depth face to face interviews. The tools used included a survey questionnaire, Focus Group Discussion guide and In‐depth Interview guide. Among the recommendations are that CSOs need to go beyond creating awareness and trainings and engage with governance issues more directly using well‐tried mechanisms.
Fighting corruption in developing countries: Some aspects of policy from lessons from the field
Authors: Hope, Kempe Ronald
Published: October 2017

Corruption persists in developing countries despite the proliferation of legal, institutional, and other measures that have been put in place to fight said corruption. The cancer of corruption has therefore spread exponentially in most developing countries with devastating socioeconomic and governance consequences. This practitioner perspective draws on the author's field experience and backed up by the research literature. It identifies, outlines, and discusses some aspects of policy in 3 areas—institution strengthening, the development and implementation of national anticorruption plans/strategies, and political will and leadership—and the conclusions that can be drawn from them for policy development and implementation in the ongoing quest to fight corruption in developing countries.
Mass Spectrometric Analysis of Cerebrospinal Fluid Ubiquitin in Alzheimer's Disease and Parkinsonian Disorders
Authors: Sjödin Simon , Hansson Oskar , Öhrfelt Annika , Brinkmalm Gunnar , Zetterberg Henrik , Brinkmalm Ann , Blennow Kaj
Published: October 2017

Purpose

Dysfunctional proteostasis, with decreased protein degradation and an accumulation of ubiquitin into aggregated protein inclusions, is a feature of neurodegenerative diseases. Identifying new potential biomarkers in cerebrospinal fluid (CSF) reflecting this process could contribute important information on pathophysiology.

Experimental design

A developed method combining SPE and PRM‐MS is employed to monitor the concentration of ubiquitin in CSF from subjects with Alzheimer's disease (AD), Parkinson's disease (PD), and progressive supranuclear palsy (PSP). Four independent cross‐sectional studies are conducted, studies 1–4, including controls (n = 86) and participants with AD (n = 60), PD (n = 15), and PSP (n = 11).

Results

The method shows a repeatability and intermediate precision not exceeding 6.1 and 7.9%, respectively. The determined LOD is 0.1 nm and the LOQ range between 0.625 and 80 nm. The CSF ubiquitin concentration is 1.2–1.5‐fold higher in AD patients compared with controls in the three independent AD‐control studies (Study 1, p < 0.001; Study 2, p < 0.001; and Study 3, p = 0.003). In the fourth study, there is no difference in PD or PSP, compared to controls.

Conclusion and clinical relevance

CSF ubiquitin may reflect dysfunctional proteostasis in AD. The described method can be used for further exploration of ubiquitin as a potential biomarker in neurodegenerative diseases.
Large cosolutes, small cosolutes, and dihydrofolate reductase activity
Authors: Acosta Luis C. , Perez Goncalves Gerardo M. , Pielak Gary J. , Gorensek‐Benitez Annelise H.
Published: October 2017

Protein enzymes are the main catalysts in the crowded and complex cellular interior, but their activity is almost always studied in dilute buffered solutions. Studies that attempt to recreate the cellular interiorin vitrooften utilize synthetic polymers as crowding agents. Here, we report the effects of the synthetic polymer cosolutes Ficoll, dextran, and polyvinylpyrrolidone, and their respective monomers, sucrose, glucose, and 1‐ethyl‐2‐pyrrolidone, on the activity of the 18‐kDa monomeric enzyme,Escherichia colidihydrofolate reductase. At low concentrations, reductase activity increases relative to buffer and monomers, suggesting a macromolecular effect. However, the effect decreases at higher concentrations, approaching, and, in some cases, falling below buffer values. We also assessed activity in terms of volume occupancy, viscosity, and the overlap concentration (where polymers form an interwoven mesh). The trends vary with polymer family, but changes in activity are within threefold of buffer values. We also compiled and analyzed results from previous studies and conclude that alterations of steady‐state enzyme kinetics in solutions crowded with synthetic polymers are idiosyncratic with respect to the crowding agent and enzyme.
Bilateral tubal pregnancies after a single‐embryo transfer
Authors: Sugawara Nobuo , Sato Rie , Kato Mika , Manome Tomomi , Kimura Yasuyuki , Araki Yasuhisa , Araki Yasuyuki
Published: October 2017

Case

To present an extremely rare case of bilateral tubal pregnancies following a single‐embryo transfer in a woman with a 4 year history of infertility prior to seeking assisted reproductive technology.

Outcome

A pregnancy resulted from the transfer of an embryo that had been thawed from a frozen blastocyst during a hormone replacement cycle. An ultrasound that was performed at 5 weeks and 5 days of gestation revealed a gestational sac, embryo, and heartbeat in the right fallopian tube and similar signs of a gestational sac in the left fallopian tube. A laparoscopy revealed clear signs of an ectopic pregnancy in the ampulla of the right fallopian tube. Signs of swelling also were seen in the ampulla of the left fallopian tube. As the possibility of bilateral tubal pregnancies could not be ruled out, both fallopian tubes were removed. Pathological tests revealed chorionic villi and trophoblasts in both the left and right fallopian tubes.

Conclusion

All previously reported cases of bilateral tubal pregnancies have been a result of multiple ovulations or multiple‐embryo transfer and no case of bilateral tubal pregnancies after a single‐embryo transfer has ever been reported. No genetic testing was performed; thus, it cannot be definitively stated that the divided chorionic villi and trophoblasts came from only one embryo.
On input‐to‐state stability of rigid‐body attitude control with quaternion representation
Authors: Hu Jinchang , Zhang Honghua
Published: October 2017

The concept of input‐to‐state stability (ISS) is important in robust control, as the state of an ISS system subject to disturbances can be stably regulated to a small region around the origin. In this study, the ISS property of the rigid‐body attitude system with quaternion representation is thoroughly investigated. It has been known that the closed loop with continuous controllers is not ISS with respect to arbitrarily small external disturbances. To deal with this problem, hybrid proportional‐derivative controllers with hysteresis are proposed to render the attitude system ISS. The controller is far from new, but it is investigated in a new aspect. To illustrate the applications of the results about ISS, 2 new robust hybrid controllers are designed. In the case of large bounded time‐varying disturbances, the hybrid proportional‐derivative controller is designed to incorporate a saturated high‐gain feedback term, and arbitrarily small ultimate bounds of the state can be obtained; in the case of constant disturbances, a hybrid adaptive controller is proposed, which is robust against small estimate error of inertia matrix. Finally, simulations are conducted to illustrate the effectiveness of the proposed control strategies.
Solvability conditions and design for synchronization of discrete‐time multiagent systems
Authors: Stoorvogel Anton A. , Saberi Ali , Zhang Meirong , Liu Zhenwei
Published: October 2017

This paper provides solvability conditions for state synchronization with homogeneous discrete‐time multiagent systems with a directed and weighted communication network under partial‐ or full‐state coupling. Our solvability conditions reveal that the synchronization problem is solvable for all possible, a priori given, set of graphs associated with a communication network only under the condition that the agents are at most weakly unstable (ie, agents have all eigenvalues in the closed unit disc). However, if an upper bound on the eigenvalues inside the unit disc of the row stochastic matrices associated with any graph in a given set of graphs is known, then one can achieve synchronization for a class of unstable agents. We provide protocol design for at most weakly unstable agents based on a direct eigenstructure assignment method and a standard H2 discrete‐time algebraic Riccati equation. We also provide protocol design for strictly unstable agents (ie, agents have at least one eigenvalue outside the unit disc) based on the standard H2 discrete‐time algebraic Riccati equation.
The AutoSOAR autonomous soaring aircraft part 2: Hardware implementation and flight results
Authors: Depenbusch Nathan T. , Bird John J. , Langelaan Jack W.
Published: October 2017

Autonomous soaring has the potential to greatly improve both the range and endurance of small robotic aircraft. This paper describes the results of a test flight campaign to demonstrate an autonomous soaring system that generates a dynamic map of lift sources (thermals) in the environment and uses this map for on‐line flight planning and decision making. The aircraft is based on a commercially available radio‐controlled glider; it is equipped with an autopilot module for low‐level flight control and on‐board computer that hosts all autonomy algorithms. Components of the autonomy algorithm include thermal mapping, explore/exploit decision making, navigation, optimal airspeed computation, thermal centering control, and energy state estimation. A finite state machine manages flight behaviors and switching between behaviors. Flight tests at Aberdeen Proving Ground resulted in 7.8 h flight time with the autonomous soaring system engaged, with three hours spent climbing in thermals. Postflight computation of energy state and frequent observations of groups of birds thermalling with our aircraft indicate that it was effectively exploiting available energy.
Learning to Write With Interactive Writing Instruction
Authors: Williams Cheri
Published: October 2017

Interactive writing is a process‐oriented instructional approach designed to make the composing and encoding processes of writing overt and explicit for young students who are learning to write. It is particularly suitable for students who struggle with literacy learning. This article describes one first‐grade teacher's use of interactive writing to teach her students what it means to write and how they could go about it. The project documents the writing processes, conventions, and strategies that the teacher taught during interactive writing lessons across one academic year and illustrates how the students learned and subsequently used those conceptual tools to mediate their independent writing. Results of the project demonstrate the expediency of interactive writing instruction for supporting the learning‐to‐write process and hold important implications for writing instruction in the early childhood program.
Detection of faulty high speed wind turbine bearing using signal intensity estimator technique
Authors: Elforjani Mohamed , Shanbr Suliman , Bechhoefer Eric
Published: October 2017

Bearings are typically used in wind turbines to support shafts and gears that increase rotational speed from a low speed rotor to a higher speed electrical generator. For various bearing applications, condition monitoring using vibration measurements has remained a subject of intense study to the present day since several decades. Various signal processing techniques are used to analyse vibration signals and extract features related to defects. Statistical indicators such as Crest Factor (CF) and Kurtosis (KU) were reported as very sensitive indicators when the presence of the defects is pronounced, whilst their values may come down to the level of undamaged components when the damage is well advanced. Further, these indicators were applied to an acquired data from proposed diagnostic models, test rigs, and instrumentations that were specifically used for particular research tests, and thus, it is essential to undertake further investigations and analysis to assess the influence of other factors such as the structural noise and other operating conditions on the real‐world applications. With this in mind, the present work proposes Signal Intensity Estimator (SIE) as a new technique to discriminate individual types of early natural damage in real‐world wind turbine bearings. Comparative results between SIE and conventional indicators such as KU and CF are also presented. It was concluded that SIE has an advantage over the other fault indicators if sufficient data are provided.

Published: October 2017

A new rigid metal‐organic framework (MOF) with MIL‐53 topology built of 2,5‐thiophenedicarboxylate (TDC) and Al, Ga, or In is reported. Its structure contains chains of trans corner sharing MO6 octahedra, connected by the linker molecules to form microporous square shaped 1D channels. A combination of powder X‐ray diffraction (PXRD), density functional theory (DFT) calculations, and 1H, 13C, and 27Al solid‐state NMR spectroscopy (ssNMR) was used to analyse the structures in detail. The synthesis is easily scaled‐up using microwave assisted solvothermal conditions. All materials possess a high thermal stability up to 420 °C in air and permanent porosity towards N2, H2, CO2, and CH4. Al‐MIL‐53‐TDC shows a high specific surface area of as,BET = 1150 m2·g–1 with a micropore volume of Vmic = 0.48 cm3·g–1 as well as water uptake of 5.5H2O molecules per sum formula (469 mg·g–1) with an a sigmoidal shape, advantageous for heat‐transformation processes. Noteworthy, this material adsorbs 2.1 wt % H2 at –196 °C and 1 bar, which surpasses other Al‐MIL‐53 compounds based on linear functionalized terephthalates.
Geometry and Complexity Theory
Authors: Landsberg J. M.
Published: October 2017

Two central problems in computer science are P vs NP and the complexity of matrix multiplication. The first is also a leading candidate for the greatest unsolved problem in mathematics. The second is of enormous practical and theoretical importance. Algebraic geometry and representation theory provide fertile ground for advancing work on these problems and others in complexity. This introduction to algebraic complexity theory for graduate students and researchers in computer science and mathematics features concrete examples that demonstrate the application of geometric techniques to real world problems. Written by a noted expert in the field, it offers numerous open questions to motivate future research. Complexity theory has rejuvenated classical geometric questions and brought different areas of mathematics together in new ways. This book will show the beautiful, interesting, and important questions that have arisen as a result.
The Mortal Voice in the Tragedies of Aeschylus
Authors: Nooter Sarah
Published: October 2017

Voice connects our embodied existence with the theoretical worlds we construct. This book argues that the voice is a crucial element of mortal identity in the tragedies of Aeschylus. It first presents conceptions of the voice in ancient Greek poetry and philosophy, understanding it in its most literal and physical form, as well as through the many metaphorical connotations that spring from it. Close readings then show how the tragedies and fragments of Aeschylus gain meaning from the rubric and performance of voice, concentrating particularly on the Oresteia. Sarah Nooter demonstrates how voice - as both a bottomless metaphor and performative agent of action - stands as the prevailing configuration through which Aeschylus' dramas should be heard. This highly original book will interest all those interested in classical literature as well as those concerned with material approaches to the interpretation of texts.
Cephalopod prey of two demersal sharks caught in the Aegean Sea (eastern Mediterranean)

Published: October 2017

This study concerns the cephalopod species that are part of the diet of the small-spotted catshark Scyliorhinus canicula and the longnose spurdog Squalus blainville sampled by commercial trawlers in the Aegean Sea from 2005 to 2012. Based on the examined cephalopod beaks, 15 species were identified belonging in six families of Teuthida, one of Sepiida and two of Octopoda. The diversity of cephalopod prey species was higher for S. canicula (N = 15) than for S. blainville (N = 10). Nektonic cephalopods comprised the majority (>72%) of the preyed species by both sharks, among which about 55% inhabit the demersal zone and 45% the mesopelagic. In the diet of S. canicula, the demersal squid Illex coindetii and the pelagic sepiolid Heteroteuthis dispar were equally represented composing 20% of prey specimens, followed by the small-sized squid Abralia veranyi and the demersal sepiolid Rossia macrosoma. The latter species was substituted in the diet of S. blainville by the demersal medium-sized octopod Scaeurgus unicirrhus, which with the equally represented three other species, composed 50% of the cephalopod prey. Differences observed between S. canicula and S. blainville in the condition of beaks retained in their stomach contents and in the variation of prey species diversity by predator specimen size, may imply differences in their foraging tactics (hunting for prey vs scavenging on the bottom), habitats and stomach evacuation frequency.
A Silver Service and a Gold Coin
Authors: Walsh Justin St P.
Published: October 2017

The published history of a set of silver and gold objects acquired by the J. Paul Getty Museum in 1975 contains an unusual reference to a gold coin, supposedly found with the set but not purchased by the museum. The coin, which is both rare and well dated, ostensibly offers a date and location for the ancient deposition of the silver service. Almost five years of research into the stories of the Getty objects and the coin has revealed important information about these particular items, but it also offers a cautionary example for scholars who might hope to reconstruct the find-spot of antiquities that are likely to have been looted.
‘To Beare the Towne Harmles’: Manorial Regulation of Mobility and Settlement in Early Modern Lancashire
Authors: WATSON CHRIS
Published: October 2017

This article examines the role of manorial courts in early modern Lancashire in the regulation of mobility through order making in relation to inmates. The period under consideration is c. 1550–c. 1660. Four aspects of their operation are considered: the volume of court business dealing with issues of mobility, the quality of court orders regulating it, the place of the manor court in the topography of local governance and aspects of continuity and change in the courts’ functioning in the period. Manorial courts are shown to be active and innovative constituents of the local administrative landscape, exercising a role wider than merely the imposition of seigneurial interest and control.
The Agricultural Credit System in the Ottoman Empire between 1863 and 1888
Authors: DOKUZLU SERTAÇ
Published: October 2017

Agricultural credit organisations are paramount to every country because agriculture must operate under threats of risk and uncertainty. When small-scale family farms are dominant, all types of agricultural organisations become important to keep farmers’ incomes at a reasonable level and encourage agricultural development. Midhat Pasha understood the importance of agricultural organisations, and he created a well-designed system for agricultural credit. He is the founder of Homeland Coffers that distribute credits to farmers. The original side of these credit organisations was capital accumulation and the methods of using it. Capital for these Coffers were provided by the joint actions of credit users. Midhat Pasha connected two cooperatives while the production cooperative provided capital for Homeland Coffers, they operated as a credit cooperative for twenty-five years in the Ottoman Empire. This credit organisation helped development of agriculture and provided many social benefits to the rural area.

An annotated dataset of Egyptian fruit bat vocalizations across varying contexts and during vocal ontogeny
Authors: Prat Yosef , Taub Mor , Pratt Ester , Yovel Yossi
Published: October 2017

Animal acoustic communication research depends on our ability to record the vocal behaviour of different species. Only rarely do we have the opportunity to continuously follow the vocal behaviour of a group of individuals of the same species for a long period of time. Here, we provide a database of Egyptian fruit bat vocalizations, which were continuously recorded in the lab in several groups simultaneously for more than a year. The dataset includes almost 300,000 files, a few seconds each, containing social vocalizations and representing the complete vocal repertoire used by the bats in the experiment period. Around 90,000 files are annotated with details about the individuals involved in the vocal interactions, their behaviours and the context. Moreover, the data include the complete vocal ontogeny of pups, from birth to adulthood, in different conditions (e.g., isolated or in a group). We hope that this comprehensive database will stimulate studies that will enhance our understanding of bat, and mammal, social vocal communication.

Published: October 2017

Animal models of psychosis propose that abnormal hippocampal activity drives increased subcortical dopamine function, which is thought to contribute to aberrant salience processing and psychotic symptoms. These effects appear to be mediated through connections between the hippocampus, ventral striatum/pallidum and the midbrain. The aim of the present study was to examine the activity and connectivity in this pathway in people at ultra high risk (UHR) for psychosis. Functional magnetic resonance imaging was used to compare neural responses in a hippocampal–basal ganglia–midbrain network during reward, novelty and aversion processing between 29 UHR subjects and 32 healthy controls. We then investigated whether effective connectivity within this network is perturbed in UHR subjects, using dynamic causal modelling (DCM). Finally, we examined the relationship between alterations in activation and connectivity in the UHR subjects and the severity of their psychotic symptoms. During reward anticipation, UHR subjects showed greater activation than controls in the ventral pallidum bilaterally. There were no differences in activation during novelty or aversion processing. DCM revealed that reward-induced modulation of connectivity from the ventral striatum/pallidum to the midbrain was greater in UHR subjects than controls, and that in UHR subjects, the strength of connectivity in this pathway was correlated with the severity of their abnormal beliefs. In conclusion, ventral striatal/pallidal function is altered in people at UHR for psychosis and this is related to the level of their psychotic symptoms.
