IT has considerable importance for productivity increase and growth. IT use requires a lot of resources to create value. Few, if any, studies, take the perspective of SMEs' needs for infrastructure concerning use of IT. As resources are more limited in smaller enterprises, and the contexts and conditions for IT use in SMEs are not well known. Formative infrastructure is a way of understanding cognitive and technical arrangements needed for IT adoption and use, depending on IT resources crossing organizational boundaries. The purpose is to study conditions for IT-use in SMEs for a better understanding of how a formative infrastructure contributes to enterprises. The methodological point of departure and approach in this study is qualitative and explorative. More than 60 interviews are performed within a geographical region. Questions concern needs for infrastructure among SMEs, actors roles, and concepts constituting a formative infrastructure for IT adoption and use. Data was analyzed for similarities and patterns into themes and topics. A theoretical framework for formative infrastructure is presented as a multi theory lens for developing the concept of formative infrastructure. A formative IT infrastructure is constituted by the identified needs among SMEs, and it contains three parts; (1) sensemaking, (2) senegiving, and (3) service infrastructures. Formative IT infrastructure in SMEs is not a well known concept, concerning IT use in SME's. The need of for formative infrastructure in sensemaking IT adoption and use in SME's rely on external partners and other actors for sensemaking and sensegiving processes. Further research is needed for better understanding of actors and roles as well as arenas for sensemaking IT in SMEs. The emphasis on infrastructure for IT adoption processes will help SME's to more relevant investments.
[Observation of clinical curative effect of "oblique-pulling" maneuver in the treatment of lumbar intervertebral disc herniation].

OBJECTIVE
To evaluate the clinical curative effect of "oblique-pulling" maneuver in patients with lumbar intervertebral disc herniation (LIDH).


METHODS
Sixty-five LIDH cases were randomly divided into experimental group and control group. In the experimental group 32 patients were treated by "oblique-pulling" maneuver, and 32 patients in the control group were treated by lumbar traction therapy. One case were excluded from the study and another one case were dropped from the study. After one course of treatment, the therapeutic effects of the two groups were compared quantitatively by using the JOA and VAS scores, including the improvement of signs, symptoms, living ability, and low back and leg pain.


RESULTS
After one course of treatment, in the experimental group, 7 cases were controlled well, 16 cases were marked effect, 8 cases were effect, 1 case was no effect. In the control group, 4 cases were controlled well, 10 cases were marked effect, 13 cases were effect, 4 cases was no effect in control group. The clinical effective rate of the experimental group was 96.86%, which was higher than 87.10% of the control group (P < 0.05). In the experimental group the scores of JOA and VAS were obviously improved after treatment (P < 0.001) and the improvement was better than that of control group (P < 0.01).


CONCLUSION
The "oblique-pulling" maneuver has the characteristics of simple operation, repeatability, good efficiency, high safety.

A Time-Varying Convergence Parameter for the LMS Algorithm in the Presence of White Gaussian Noise

A novel approach for the least-mean-square (LMS) estimation algorithm is proposed. Rather than using a fixed convergence parameter μ, this approach utilizes a time-varying LMS parameter μn. This technique leads to faster convergence and provides reduced mean-squared error compared to the conventional fixed parameter LMS algorithm. The algorithm has been tested for noise reduction and estimation in narrow-band FM signals corrupted by additive white Gaussian noise.
The challenges of SVM optimization using Adaboost on a phoneme recognition problem

The use of digital technology is growing at a very fast pace which led to the emergence of systems based on the cognitive infocommunications. The expansion of this sector impose the use of combining methods in order to ensure the robustness in cognitive systems.
Nonexistence of certain binary orthogonal arrays

We prove that binary orthogonal arrays of strength 8, length 12 and cardinality 1536 do not exist. This implies the nonexistence of arrays of parameters (strength,length,cardinality) = (n, n + 4, 6.2) for every integer n ≥ 8.
Compositional Learning of Embeddings for Relation Paths in Knowledge Base and Text

Modeling relation paths has offered significant gains in embedding models for knowledge base (KB) completion. However, enumerating paths between two entities is very expensive, and existing approaches typically resort to approximation with a sampled subset. This problem is particularly acute when text is jointly modeled with KB relations and used to provide direct evidence for facts mentioned in it. In this paper, we propose the first exact dynamic programming algorithm which enables efficient incorporation of all relation paths of bounded length, while modeling both relation types and intermediate nodes in the compositional path representations. We conduct a theoretical analysis of the efficiency gain from the approach. Experiments on two datasets show that it addresses representational limitations in prior approaches and improves accuracy in KB completion.
Comparison of oral ivermectin versus crotamiton 10% cream in the treatment of scabies.

OBJECTIVE
Scabies is a relatively contagious infection caused by a tiny mite (Sarcoptes scabiei). Products used to treat scabies are called scabicides because they kill scabies mites; some also kill mite eggs. The aim of this study was to compare the efficacy and safety of oral ivermectin versus crotamiton 10% cream for the treatment of scabies.


METHODS
In total, 320 patients with scabies were enrolled, and were randomized into two groups: the first group received a single dose of oral ivermectin 200 µg/kg body weight, and the second group were treated with crotamiton 10% cream and were told to apply this twice daily for five consecutive days. Treatment was evaluated at intervals of two and four weeks, and if there was treatment failure at the two-week follow-up, the treatment was repeated.


RESULTS
A single dose of ivermectin provided a cure rate of 62.5% at the two-week follow-up, which increased to 87.5% at the four-week follow-up after repeating the treatment. Treatment with crotamiton 10% cream was effective in 46.8% of patients at the two-week follow-up, which increased to 62.5% at the four-week follow-up after this treatment was repeated.


CONCLUSION
A single dose of ivermectin was as effective as one application of crotamiton 10% cream at the two-week follow-up. After repeat treatment, ivermectin was superior to crotamiton 10% cream at the four-week follow up. The delay in clinical response with ivermectin suggests that it may not be effective against all the stages in the life cycle of the parasite.
Effect of intensive therapy on the development and progression of diabetic nephropathy in the Diabetes Control and Complications Trial. The Diabetes Control and Complications (DCCT) Research Group.

The Diabetes Control and Complications Trial (DCCT) has demonstrated that intensive diabetes treatment delays the onset and slows the progression of retinopathy, nephropathy, and neuropathy in patients with IDDM. A detailed description of the effects of this treatment on diabetic nephropathy is presented here. In the primary prevention cohort, intensive treatment reduced the mean adjusted risk of the cumulative incidence of microalbuminuria (> or = 28 micrograms/min) by 34% (95% CI 2, 56%; P = 0.04). Furthermore, intensive treatment decreased the albumin excretion rate (AER) by 15% after the first year of therapy (6.5 vs. 7.7 micrograms/min, P < 0.001). Thereafter the rates of change for AER within each treatment group were no different from zero, retaining a constant difference in AER between groups in the trial. In the secondary intervention cohort with baseline AER < 28 micrograms/min, intensive therapy reduced the mean adjusted risk of microalbuminuria (> or = 28 micrograms/min) by 43% (95% CI 21, 58%; P < 0.0001); the risk of a more advanced level of microalbuminuria (> or = 70 micrograms/min) by 56% (95% CI 26, 74%; P = 0.002); and the risk of clinical albuminuria (> or = 208 micrograms/min) by 56% (95% CI 18, 76%; P < 0.01). In the secondary intervention cohort, values for AER at year 1 were identical at 9 micrograms/min, but the 6.5% change per year in the conventional group greatly exceeded the rate of change of -0.3% in the intensive group (P < 0.001). Among the 73 secondary cohort subjects with AER levels > or = 28 micrograms/min but < or = 139 micrograms/min at baseline, the reduction of progression to clinical albuminuria with intensive therapy was not statistically significant. The longitudinal treatment effect of conventional versus intensive therapy (11.0% vs. 2.5% per year, respectively, P = 0.087) was similar in magnitude to that among patients with AER < 28 micrograms/min at baseline. For the primary, secondary and combined cohorts, there were no significant differences in the rates of change in creatinine clearance (CCr) between treatment groups during the study. Only seven subjects in the entire study (2 intensive, 5 conventional) developed urinary AER > or = 208 micrograms/min coupled with a CCr < 70 ml/min/1.73 m2. Neither the rate of change of blood pressure nor the appearance of hypertension (BP > 140/90 mm Hg) differed significantly between treatment groups in the primary, secondary or combined cohorts.(ABSTRACT TRUNCATED AT 400 WORDS)

A Learning-based Variable Size Part Extraction Architecture for 6D Object Pose Recovery in Depth

State-of-the-art techniques for 6D object pose recovery depend on occlusion-free point clouds to accurately register objects in 3D space. To deal with this shortcoming, we introduce a novel architecture called Iterative Hough Forest with Histogram of Control Points that is capable of estimating the 6D pose of an occluded and cluttered object, given a candidate 2D bounding box. Our Iterative Hough Forest (IHF) is learnt using parts extracted only from the positive samples. These parts are represented with Histogram of Control Points (HoCP), a “scale-variant” implicit volumetric description, which we derive from recently introduced Implicit B-Splines (IBS). The rich discriminative information provided by the scale-variant HoCP features is leveraged during inference. An automatic variable size part extraction framework iteratively refines the object’s roughly aligned initial pose due to the extraction of coarsest parts, the ones occupying the largest area in image pixels. The iterative refinement is accomplished based on finer (smaller) parts, which are represented with more discriminative control point descriptors by using our Iterative Hough Forest. Experiments conducted on a publicly available dataset report that our approach shows better registration performance than the state-of-the-art methods. © 2017 Elsevier B.V. All rights reserved.
COTS-Aware Requirements Engineering and Software

At the heart of a well-disciplined, systematic methodology that explicitly supports the use of COTS components is a clearly defined process for effectively using components that meet the needs of the system under development. In this paper, we present the CARE/SA approach which supports the iterative matching, ranking, and selection of COTS components, using a representation of COTS components as an aggregate of their functional and non-functional requirements and architecture. The approach is illustrated using a Digital Library System example. 1 This is an extended and improved version of [8]; this extension considers both functional and non-functional requirements as candidates for the matching, ranking, and selection process.
Stress and Coping in Women Living with HIV: A Meta-Analytic Review

To examine effects between stressors and coping mechanisms on behavioral health outcomes a meta-analysis was conducted using forty empirical articles which sampled 7,602 adult women living with HIV/AIDS in the U.S. (M = 36.3 years). Three independent reviewers conducted searches in abstract databases from 1997 to present day. Articles reporting effect sizes amongst psychosocial stressors and coping mechanisms with indices of behavioral/mental health were selected. The meta-analyses revealed that in a time frame characterized by the widespread availability of anti-retroviral medication, poor mental health outcomes were predicted, in a similar manner, by psychosocial stress and HIV/AIDS symptomology. Significant effects were also observed with functional impairment, though to a lesser degree. Coping by avoidance and social isolation predicted more severe mental health outcomes. Spirituality and positive reappraisal predicted greater psychological adaptation than did social support seeking. Despite advancements in anti-retroviral treatment for women, HIV/AIDS symptoms and acute and/or chronic psychosocial stress pose the same threat to behavioral and mental health. In the face of these stressors, positive reframing appears to promote psychological adaptation in a way which may lead to positive health outcomes in women living with HIV/AIDS. En este meta-análisis se examinó el efecto que el estrés y los mecanismos de adaptación tienen sobre el ajuste a la enfermedad; se utilizaron cuarenta artículos empíricos que incluyeron un total de 7.602 mujeres adultas que sufrían de VIH/SIDA (Medad = 36,3 años). Tres revisores hicieron independientemente hicieron búsquedas en bases de datos de artículos publicados desde 1997 a la actualidad. Se escogieron artículos que describían el tamaño del efecto en el estrés psicosocial, en los mecanismos de adaptacion con índices de salud mental o conductual. Tanto el estrés psicosocial como la sintomatología de HIV/AIDS predijeron una inapropiada salud mental. En menor grado se observaron alteraciones en el funcionamiento. El enfrentarse a la enfermedad a través del aislamiento social y la evitación predijeron el desajuste en la salud mental de HIV/AIDS. La espiritualidad y reevaluación positiva predijeron mejor el afecto positivo que la búsqueda de apoyo social. A pesar de los avances en la terapia HAART, el estrés psicosocial agudo y crónico asociado a los síntomas de HIV/AIDS, continúa contribuyendo a la psicopatología y a la presencia de conductas de salud desviadas en mujeres con HIV/AIDS. Estas mujeres emplean una multitud de mecanismos de adaptación para amortiguar los efectos del estrés.
Treatment of a retrobulbar abscess secondary to dental associated infection in a rabbit

Dental disease is a common problem of pet rabbits. Some authors have postulated that nearly 100% of pet rabbits will develop some form of acquired dental disease (ADD) in their lifetime. Dental disease may affect rabbits of any age and gender and can be a cause of great morbidity and malaise. Often dental disease may lead to infection of teeth and surrounding structures. The development of infection and abscessation often heralds a guarded to poor prognosis for resolution unless affected teeth are extracted, infected tissue is resected and supportive and medical therapy are employed.
Therapeutic alliance mediates the association between personality and treatment outcome in patients with major depressive disorder.

BACKGROUND
Patient personality traits have been shown to influence treatment outcome in those with major depressive disorder (MDD). The trait agreeableness, which reflects an interpersonal orientation, may affect treatment outcome via its role in the formation of therapeutic alliance. No published studies have tested this hypothesis in patients with MDD.


METHOD
Participants were 209 outpatients with MDD who were treated in a randomized control trial. Mediation analyses were conducted to examine the role of therapeutic alliance in the association between pretreatment personality and the reduction of depression symptom severity during treatment. Separate models were estimated for patient- versus therapist-rated therapeutic alliance.


RESULTS
We found a significant indirect effect of agreeableness on the reduction of depression severity via patient-rated therapeutic alliance. Results were replicated across two well-validated measures of depression symptom severity. Results also partially supported indirect effects for extraversion and openness. Therapist ratings of alliance did not mediate the association between personality and treatment outcomes.


LIMITATIONS
Patients were recruited as part of a randomized control trial, which may limit the generalizability of results to practice-based clinical settings. Due to constraints on statistical power, intervention-specific mediation results were not examined.


CONCLUSIONS
These results highlight the importance of personality and the role it plays in treatment process as well as outcome.
Stability of networked control systems

IEEE Control Systems Magazine February 2001 Feedback control systems wherein the control loops are closed through a real-time network are called networked control systems (NCSs) [1]-[4]. The defining feature of an NCS is that information (reference input, plant output, control input, etc.) is exchanged using a network among control system components (sensors, controller, actuators, etc.). Fig. 1 illustrates a typical setup and the information flows of an NCS. The primary advantages of an NCS are reduced system wiring, ease of system diagnosis and maintenance, and increased system agility. The insertion of the communication network in the feedback control loop makes the analysis and design of an NCS complex. Conventional control theories with many ideal assumptions, such as synchronized control and nondelayed sensing and actuation, must be reevaluated before they can be applied to NCSs. Specifically, the following issues need to be addressed. The first issue is the network-induced delay (sensor-to-controller delay and controller-to-actuator delay) that occurs while exchanging data among devices connected to the shared medium. This delay, either constant (up to jitter) or time varying, can degrade the performance of control systems designed without considering the delay and can even destabilize the system. Next, the network can be viewed as a web of unreliable transmission paths. Some packets not only suffer transmission delay but, even worse, can be lost during transmission. Thus, how such packet Stability of Networked Control Systems By Wei Zhang, Michael S. Branicky, and Stephen M. Phillips
Branched-chain amino acids reduce hepatic iron accumulation and oxidative stress in hepatitis C virus polyprotein-expressing mice

BACKGROUND & AIMS
Branched-chain amino acids (BCAA) reduce the incidence of hepatocellular carcinoma (HCC) in patients with cirrhosis. However, the mechanisms that underlie these effects remain unknown. Previously, we reported that oxidative stress in male transgenic mice that expressed hepatitis C virus polyprotein (HCVTgM) caused hepatic iron accumulation by reducing hepcidin transcription, thereby leading to HCC development. This study investigated whether long-term treatment with BCAA reduced hepatic iron accumulation and oxidative stress in iron-overloaded HCVTgM and in patients with HCV-related advanced fibrosis.


METHODS
Male HCVTgM were fed an excess-iron diet that comprised either casein or 3.0% BCAA, or a control diet, for 6 months.


RESULTS
For HCVTgM, BCAA supplementation increased the serum hepcidin-25 levels and antioxidant status [ratio of biological antioxidant potential (BAP) relative to derivatives of reactive oxygen metabolites (dROM)], decreased the hepatic iron contents, attenuated reactive oxygen species generation, and restored mitochondrial superoxide dismutase expression and mitochondrial complex I activity in the liver compared with mice fed the control diet. After 48 weeks of BCAA supplementation in patients with HCV-related advanced fibrosis, BAP/dROM and serum hepcidin-25 increased and serum ferritin decreased compared with the pretreatment levels.


CONCLUSIONS
BCAA supplementation reduced oxidative stress by restoring mitochondrial function and improved iron metabolism by increasing hepcidin-25 in both iron-overloaded HCVTgM and patients with HCV-related advanced fibrosis. These activities of BCAA may partially account for their inhibitory effects on HCC development in cirrhosis patients.
