GPU Array Access Auto-Tuning

GPUs have been used for years in compute intensive applications. Their massive parallel processing capabilities can speedup calculations significantly. However, to leverage this speedup it is necessary to rethink and develop new algorithms that allow parallel processing. These algorithms are only one piece to achieve high performance. Nearly as important as suitable algorithms is the actual implementation and the usage of special hardware features such as intra-warp communication, shared memory, caches, and memory access patterns. Optimizing these factors is usually a time consuming task that requires deep understanding of the algorithms and the underlying hardware. Unlike CPUs, the internal structure of GPUs has changed significantly and will likely change even more over the years. Therefore it does not suffice to optimize the code once during the development, but it has to be optimized for each new GPU generation that is released. To efficiently (re-)optimize code towards the underlying hardware, auto-tuning tools have been developed that perform these optimizations automatically, taking this burden from the programmer. In particular, NVIDIA -- the leading manufacturer for GPUs today -- applied significant changes to the memory hierarchy over the last four hardware generations. This makes the memory hierarchy an attractive objective for an auto-tuner. In this thesis we introduce the MATOG auto-tuner that automatically optimizes array access for NVIDIA CUDA applications. In order to achieve these optimizations, MATOG has to analyze the application to determine optimal parameter values. The analysis relies on empirical profiling combined with a prediction method and a data post-processing step. This allows to find nearly optimal parameter values in a minimal amount of time. Further, MATOG is able to automatically detect varying application workloads and can apply different optimization parameter settings at runtime. To show MATOG's capabilities, we evaluated it on a variety of different applications, ranging from simple algorithms up to complex applications on the last four hardware generations, with a total of 14 GPUs. MATOG is able to achieve equal or even better performance than hand-optimized code. Further, it is able to provide performance portability across different GPU types (low-, mid-, high-end and HPC) and generations. In some cases it is able to exceed the performance of hand-crafted code that has been specifically optimized for the tested GPU by dynamically changing data layouts throughout the execution.
How do supervising physicians decide to entrust residents with unsupervised tasks? A qualitative analysis.

BACKGROUND Medical supervisors struggle to find meaningful ways to evaluate the preparedness of trainees to independently perform patient care tasks. The aim of this study was to describe the factors that influence how attending and resident physician perceptions of trust impact decision making. METHODS Internal medicine residents and attending physicians at a tertiary academic medical center were interviewed during a single academic year. Participants were asked to describe, using the critical incident technique, entrustment decisions made during their clinical rotations. A deductive qualitative analysis using the entrustable professional activities framework was used. The inter-rater reliability was calculated using a generalized kappa statistic. RESULTS Eighty-four percent (46/50) of residents and 88% (44/50) of attending physicians participated. The analysis yielded 535 discrete mentions of entrusting factors that were mapped to the following domains deductively, with inductively derived subthemes: trainee factors (eg, confidence, specialty plans), supervisor factors (eg, approachability), task factors (eg, situational characteristics) and systems factors (eg, workload). The inter-rater kappa between the 2 raters was 0.84. CONCLUSIONS Factors influencing trust in a trainee are related to the supervisor, trainee, their relationship, task, and the environment. Attending physicians note early interactions and language cues as markers of trustworthiness. Attending physicians reported using perceived confidence as a gauge of the trainee's true ability and comfort. Attendings noted trainee absences, even those that comply with regulation, negatively affected willingness to entrust. Future studies are needed to develop better assessment instruments to understand how entrustment decisions for independent practice are made.
Tracking Ultrafast Energy Flow in Molecules Using Broadly Tunable Few-Optical-Cycle Pulses

Many (bio) molecules, following light absorption, undergo ultrafast nonradiative decay processes, taking place over timescales of tens to hundreds of femtoseconds. Ultrafast optical spectroscopy allows tracking in real time this energy flow using broadly tunable few-optical-cycle light pulses. Optical parametric amplifiers, thanks to their broad and tunable gain bandwidths, are powerful tools for the generation of such pulses. This paper first reviews our work on broadband optical parametric amplifiers, which led to the demonstration of few-optical-cycle sub-10-fs pulses continuously tunable from the visible (500 nm) to the near-IR (2 μm). We then present selected examples of applications to ultrafast spectroscopy of molecules, such as isomerization of rhodopsin, carotenoid-bacteriochlorophyll energy transfer in light-harvesting complexes, and polymer-fullerene electron transfer in blends for organic photovoltaics.
Kinematics for the whole arm of a serial-chain manipulator

This paper provides a viewpoint for kinematics for the whole arm of a serial-chain manipulator with 2-d.o. f. rotational joints. An in-depth understanding of the duality between a rigid link and a 2-d.o. f. joint allows us to derive simple and geometric equations describing the manipulator kinematics. The obtained kinematic equations are analyzed in two ways compared with the Frenet-Serret formula of a spatial curve which is utilized for a reference shape of the manipulator. One way is based on limit analysis where we increase the number of joints while the total length of the manipulator remains constant. The other way utilizes an extended mechanism through the link-joint duality. The information presented in this paper is useful for mechanism design dynamic analysis, control design and motion planning of the manipulators in whole-arm manipulation.
The semiclassical coherent state propagator for systems with spin

We derive the semiclassical limit of the coherent state propagator for systems with two degrees of freedom of which one degree of freedom is canonical and the other a spin. Systems in this category include those involving spin–orbit interactions and the Jaynes–Cummings model in which a single electromagnetic mode interacts with many independent two-level atoms. We construct a path integral representation for the propagator of such systems and derive its semiclassical limit. As special cases we consider separable systems, the limit of very large spins and the case of spin-1/2.
Integrating GSO and SAW ontologies to enable Situation Awareness in Green Fleet Management

The definition of a Situation Awareness system is a challenging task that must be guided by some design principles like, for instance, organizing information around goals and supporting trade-off between goal-driven and data-driven information processing. This paper reports the results about the definition of a system for Green Fleet Management that synergistically exploits goal-driven and data-driven information processing to support Situation Awareness. These results are achieved by defining a framework based on the integration of several existing ontologies, which formalize and link actionable knowledge on goals and situations, with agents able to perform inference on it. Such a framework, which is generally applicable to heterogeneous domains, is also one of the main results of this work. The system has been evaluated by using the SAGAT method.
Reversal of tubo‐ovarian atypical epithelial patterns after cessation of ovarian stimulation by letrozole

Letrozole (LTZ), one of the ovulation induction medications, is increasingly prescribed in various gynaecological conditions. Previous studies have demonstrated its potential hazardous effect on the ovarian surface epithelium (OSE) as well as on tubal epithelial cells (TEC). However, it is not clear whether this effect could be reversed by LTZ cessation. Therefore, the objective of our study was to investigate the effect of stoppage of LTZ on these cells after 12 cycles of ovarian stimulation. A total of 54 Sprague Dawley rats were used in this study, divided equally into control, LTZ12 and CES12 groups (received saline, 12 cycles of LTZ and 12 cycles of cessation post‐LTZ12 respectively). Samples from the ovaries as well as fallopian tubes (FTs) were studied histologically for the changes associated with LTZ12 and CES12 respectively. There was evident increase in the proliferative activity and Ki67 immunoexpression in the OSE of LTZ12. The OSE was hyperchromatic, and abnormally frequent deep invaginations, micropapillae and cortical cysts. Their TEC showed frequent multilayering, papillary projections and loss of cilia. Almost all these changes disappeared 12 cycles after LTZ cessation. While the tubal IL‐1β, IL‐6, TNF‐α and serum MCP‐1 levels significantly increased in the LTZ12 group compared with the control group, their levels decreased in the CES12 group compared with those of the control. Therefore, the abnormal tubo‐ovarian epithelial patterns may completely regress after cessation of LTZ stimulation for a reasonable duration. This is a potentially good omen and a positive indicator of the relatively safe use of LTZ after its intake has been stopped.
Change of HbA1c reporting to the new SI units

TO THE EDITOR: The position statement by Jones and colleagues regarding the change of HbA 1c reporting to the new Système International (SI) units — which has been recommended by the Australasian Association of Clinical Biochemists, the Australian Diabetes Educators Association, the Australian Diabetes Society and the Royal College of Pathologists of Australasia — provides a comprehensive summary of the rationale behind the proposed change and suggests a 2-year period of dual reporting. 1 However, Jones et al did not specify targets for children and adolescents, and we believe that it is important to do so. The incidence of type 1 diabetes in Australian children and adolescents is among the highest in the world 2 and, in New South Wales, type 2 diabetes represents at least 10% of cases of new-onset diabetes in adolescents. 3 National evidence-based clinical care guidelines for type 1 diabetes in children, adolescents and adults 4 include age-specific targets for HbA 1c , while recognising that such targets are predominantly consensus based. HbA 1c targets for young people with type 1 diabetes are higher, with a level of < 7.5% recommended for children and adolescents in the Australian guidelines 4 and in those produced by the International Society for Pediatric and Adolescent Diabetes (ISPAD). 5 Jones et al note that " Achievement of HbA 1c targets must be balanced against risk of severe hypoglycaemia, especially among older people " ; 1 this is also the case for young people. For children and adolescents with type 2 diabetes, the ISPAD guidelines recommend an HbA 1c target of < 7%. 5 The move to SI units represents a major change in the established, widely recognised outcome measure of glycaemia; during the transition period, the specific needs of young people with diabetes must not be forgotten. National evidence-based clinical care guidelines for type 1 diabetes in children, adolescents and adults.ment and monitoring of glycemic control in children and adolescents with diabetes.
Laterality versus ankle dorsi- and plantarflexion maximal torques.

PURPOSE The aim of the study was to analyze the connections between the functional asymmetries of lower limbs, taking into account morphological feet features, and ankle dorsi- and plantarflexion maximal torques in men and women. METHODS The study population consisted of 56 young subjects among which there were 30 women and 26 men. The assessment of upper and lower limbs' side dominance was performed on the basis of surveys, verified with simple motor tasks that resembled the actions characteristic of the upper and lower limbs. The measurements of body build, as well as foot build, were performed with the use of accepted instruments according to the anthropometry standards. The measurements of longitudinal foot arches were conducted using the pantographic method. Ankle dorsi- and plantarflexion maximal torque values were measured under static conditions. RESULTS We found a positive correlation between the functional dominance of lower limb and greater strength only for ankle plantarflexion maximal torque values in correct laterality variants in women and in only one variant in men. No correlation was found between foot morphological asymmetry and the ankle dorsi- and plantarflexion maximal torque values, either in women or in men. CONCLUSION Our results support the idea that the functional lower limb dominance is not equivalent to the greater muscle strength.
Dumbbell-shaped iliopsoas bursitis penetrating the pelvic wall: a rare complication of hip arthrodesis. A case report.

The iliopsoas bursa is a normal anatomical structure that lies deep to the iliopsoas tendon in the region of the hip joint 1. Inflammation and distension of the bursa is most commonly associated with rheumatoid arthritis 2,3, but it is also seen in association with osteoarthrosis 2, pigmented villonodular synovitis 4, synovial chondromatosis 5, infection 6,7, pseudogout 8, and metastatic bone disease 9. In rare cases, iliopsoas bursitis develops after total hip arthroplasty 7,10-12. We report a rare case of iliopsoas bursitis that presented as a buttock mass that had completely penetrated the pelvic wall many years after hip arthrodesis. A sixty-seven-year-old woman presented with a three-year history of a painless but slowly increasing swelling in the right buttock. She had previously been diagnosed, when she was in her twenties, with bilateral coxarthrosis secondary to congenital dysplasia. She underwent arthrodesis of the right hip at thirty-four years of age and total joint arthroplasty of the left hip at fifty-seven years of age. On physical examination, a mass, measuring 22 × 18 × 10 cm, was palpated in the superolateral aspect of the right hip. The mass was nontender, well defined, nonmobile, firm, and fluctuant. Another mass, displaying similar characteristics and measuring 11 × 12 cm, was palpable medial to the right iliac crest. Both masses were firmly attached to the …

Isokinetic work-to-surface electromyographic signal energy ratios as a muscular fatigue indicator

Efficiency of muscular work is usually measured as the relationship between work load and maximum exercise duration. The present study analyzes the efficiency feature as a ratio between mechanical work (WK) and the energy (E) of the surface electromyographic signal (SEMG). This relation (WK/ESEMG) was compared with the most common electromyographic descriptors and its behavior was observed during muscle fatigue. A total of sixteen healthy men (26.8 ± 4.7 yrs, 175.7 ± 4.7 cm, and 79.2 ± 9.4 kg) performed three sets of ten maximal concentric repetitions of dominant knee extension at 60º/s on an isokinetic dynamometer, with 1 minute of rest interval between the sets. The SEMG signals were recorded during the exercises. With the view to minimize the factors other than fatigue that also influence the SEMG descriptors behavior, the only isokinetic repetition phase considered for measurements was the load range. Statistical analyses showed significant correlations between WK/ESEMG and the traditional electromyographic fatigue indicators.
A Realistic MAC and Energy Model for 802.15.4

The IEEE 802.15. 4 standard defines the physical and media access control layers for LR-WPANs (Low-Rate Wireless Personal Area Networks), and is one of the enabling technologies for Wireless Sensor Networks (WSNs) as well as the emerging Internet of Things (IoT) applications. The ns-3 network simulator offers support for simulating LR-WPANs as specified by the IEEE standard 802.15. 4 (2006). However, only the ad-hoc mode is currently supported and many important features of the MAC such as radio duty cycle management are missing from the implementation. Moreover, at the moment ns-3 does not support simulating the energy consumption of LR-WPAN devices. Since energy efficiency is an important consideration for WSN and IoT applications, support for accurate energy modeling is highly desirable in order to develop energy-aware protocols for such applications. In this paper, we present the models developed for simulating the energy consumption of nodes in LR-WPANs. Further we implement the ContikiMAC radio duty cycling protocol in order to provide a realistic 802.15. 4 compliant MAC layer which supports sleep/wake mechanisms.
Hybrid pig versus Göttingen minipig-derived cartilage and chondrocytes show pig line-dependent differences

Minipigs are widely used as a large animal model for cartilage repair. However, many in vitro studies are based on porcine chondrocytes derived from abundantly available premature hybrid pigs. It remains unclear whether pig line-dependent differences exist which could limit the comparability between in vitro and in vivo results using either hybrid or miniature pig articular chondrocytes. Porcine knee joint femoral cartilage was isolated from 3- to 5-month-old hybrid pigs and Göttingen minipigs. Cartilage from both pig lines was analysed for thickness, zonality, cell content, size and proteoglycan deposition. Cultured articular chondrocytes from both pig lines were investigated for gene and/or protein expression of cartilage-specific proteins such as type II collagen, aggrecan, the chondrogenic transcription factor Sox9, non-specific type I collagen and the cell-matrix receptor β1-integrin. Cartilage was significantly thinner in the miniature pig compared to the hybrid pig, but the differences between the medial and lateral femur condyles did not reach a significant level. Knee joint cartilage zone formation started only in the minipig, whereas cellularity and cell diameters were comparable in both pig lines. Blood vessels could be detected in the hybrid pig but not the minipig cartilage. Sulphated proteoglycan deposition was more pronounced in cartilage zones II–IV of both pig lines. Minipig chondrocytes expressed type II and I collagen, Sox9 and β1-integrin at a higher level than hybrid pig chondrocytes. These distinct line-dependent differences should be considered when using hybrid pig-derived chondrocytes for tissue engineering and Göttingen minipigs as a large animal model.
Generation of panoramic view with depth cue using image convergence technique

Panoramic mosaic has gained prominence as a two-dimensional form of seven-dimensional plenoptic function widely used for synthetic wide-angle camera. This paper proposes to take a great leap forward to improve this popular conception. Starting with either an odd or even number of images, the paper focuses on the generation of panoramic view of a scene with a significant structural difference when compared with the conventional panorama. The proposed panorama is characterized with depth cue whereby objects in the distance appear smaller than objects close by and it is realized using image convergence technique. This technique is based on the continuous division method used for the conversion of a number from one number system to another. Also the algorithm which implements this technique is characterized by accurate and reliable results, and fast implementation time.
INPATIENT COGNITIVE- BEHAVIORAL TREATMENT OF EATING DISORDER PATIENTS WITH DISSOCIATIVE DISORDERS

Although several investigations have noted an association between eating disorders and dissociative disorders, little work has addressed the treatment of patients with both conditions. As an inpatient service focused on severely-ill eating disorder patients, it became necessary to diagnose and treat concomitant dissociative disorders. We describe a cognitive-behavioral inpatient program developed and specifically adapted to treat eating disorder patients with dissociative disorders. Patients were identified by self-report measures (the Eating Disorder Inventory and the Dissociative Experiences Scale) and clinical interviews. Specificeatingsymptoms linked to post-traumatic stress or conversion disorders were approached with stimulus control and hierarchical desensitization. Individual and group cognitive therapy as well as diary techniques addressed irrational beliefs common to both disorders. Skill enhancement through relaxation training, anxiety management, and anger management, initially tailored for the eating disorder patient, required adaptation for dissociativepathology. Addressing both disorders reduced eating pathol ogy whereas inattention to dissociative symptoms led to continued disturbedeating and purging. Identification and treatment of dissociative pathology may improve treatment outcome in the treatmentresistant eating disorder patient.
Biasing CMOS amplifiers using MOS transistors in subthreshold region

The implementation of large-valued floating resistive elements using MOS transistors in subthreshold region is addressed. The application of these elements to bias wideband AC coupled amplifiers is discussed. Simple schemes to generate the gate control voltages for the MOS transistors implementing large resistors so that they remain in high resistive state with large signal variations are discussed. Experimental results of a test chip prototype in 0.5-µm CMOS technology are presented that verify the proposed technique.
HYPERSOMNIA IN DYSTROPHIA MYOTONICA

We have been interested to note the occurrence of marked hypersomnia and somnolence in four patients suffering from dystrophia myotonica. Somnolence has been described before in this condition (Rohrer, 1916; Thomasen 1948) but the association has not had much emphasis and cannot be said to be widely known. Three of our patients were known myotonic subjects in whom hypersomnia was a troublesome incidental complaint, but the fourth came complaining of fainting attacks and an unmanageable liability to oversleep, and it was only then that an unrecognized dystrophia myotonica came to light.
