Co-training is a well-known semi-supervised learning approach which trains classifiers on two or more different views and exchanges pseudo labels of unlabeled instances in an iterative way. During the co-training process, pseudo labels of unlabeled instances are very likely to be false especially in the initial training, while the standard co-training algorithm adopts a 'draw without replacement' strategy and does not remove these wrongly labeled instances from training stages. Besides, most of the traditional co-training approaches are implemented for two-view cases, and their extensions in multi-view scenarios are not intuitive. These issues not only degenerate their performance as well as available application range but also hamper their fundamental theory. Moreover, there is no optimization model to explain the objective a co-training process manages to optimize. To address these issues, in this study we design a unified self-paced multi-view co-training (SPamCo) framework which draws unlabeled instances with replacement. Two specified co-regularization terms are formulated to develop different strategies for selecting pseudo-labeled instances during training. Both forms share the same optimization strategy which is consistent with the iteration process in co-training and can be naturally extended to multi-view scenarios. A distributed optimization strategy is also introduced to train the classifier of each view in parallel to further improve the efficiency of the algorithm. Furthermore, the SPamCo algorithm is proved to be PAC learnable, supporting its theoretical soundness. Experiments conducted on synthetic, text categorization, person re-identification, image recognition and object detection data sets substantiate the superiority of the proposed method.

Abstract:
In this paper, we study the local times of vector-valued Gaussian fields that are ‘diagonally operator-self-similar’ and whose increments are stationary. Denoting the local time of such a Gaussian field around the spatial origin and over the temporal unit hypercube by $Z$, we show that there exists $lambdain(0,1)$ such that under some quite weak conditions, $lim_{n ightarrow+infty}frac{sqrt[n]{mathbb{E}(Z^{n})}}{n^{lambda}}$ and $lim_{x ightarrow+infty}frac{-logmathbb{P}(Z>x)}{x^{frac{1}{lambda}}}$ both exist and are strictly positive (possibly $+infty$). Moreover, we show that if the underlying Gaussian field is ‘strongly locally nondeterministic’, the above limits will be finite as well. These results are then applied to establish similar statements for the intersection local times of diagonally operator-self-similar Gaussian fields with stationary increments.

Abstract:
Dorie and co-authors (DHSSC) are to be congratulated for initiating the ACIC Data Challenge. Their project engaged the community and accelerated research by providing a level playing field for comparing the performance of a priori specified algorithms. DHSSC identified themes concerning characteristics of the DGP, properties of the estimators, and inference. We discuss these themes in the context of targeted learning.

Nicotine addiction, through smoking, is the principal cause of preventable mortality worldwide. Human genome-wide association studies have linked polymorphisms in the CHRNA5-CHRNA3-CHRNB4 gene cluster, coding for the α5, α3, and β4 nicotinic acetylcholine receptor (nAChR) subunits, to nicotine addiction. β4*nAChRs have been implicated in nicotine withdrawal, aversion, and reinforcement. Here we show that β4*nAChRs also are involved in non-nicotine-mediated responses that may predispose to addiction-related behaviors. β4 knock-out (KO) male mice show increased novelty-induced locomotor activity, lower baseline anxiety, and motivational deficits in operant conditioning for palatable food rewards and in reward-based Go/No-go tasks. To further explore reward deficits we used intracranial self-administration (ICSA) by directly injecting nicotine into the ventral tegmental area (VTA) in mice. We found that, at low nicotine doses, β4KO self-administer less than wild-type (WT) mice. Conversely, at high nicotine doses, this was reversed and β4KO self-administered more than WT mice, whereas β4-overexpressing mice avoided nicotine injections. Viral expression of β4 subunits in medial habenula (MHb), interpeduncular nucleus (IPN), and VTA of β4KO mice revealed dose- and region-dependent differences: β4*nAChRs in the VTA potentiated nicotine-mediated rewarding effects at all doses, whereas β4*nAChRs in the MHb-IPN pathway, limited VTA-ICSA at high nicotine doses. Together, our findings indicate that the lack of functional β4*nAChRs result in deficits in reward sensitivity including increased ICSA at high doses of nicotine that is restored by re-expression of β4*nAChRs in the MHb-IPN. These data indicate that β4 is a critical modulator of reward-related behaviors.

SIGNIFICANCE STATEMENT Human genetic studies have provided strong evidence for a relationship between variants in the CHRNA5-CHRNA3-CHRNB4 gene cluster and nicotine addiction. Yet, little is known about the role of β4 nicotinic acetylcholine receptor (nAChR) subunit encoded by this cluster. We investigated the implication of β4*nAChRs in anxiety-, food reward- and nicotine reward-related behaviors. Deletion of the β4 subunit gene resulted in an addiction-related phenotype characterized by low anxiety, high novelty-induced response, lack of sensitivity to palatable food rewards and increased intracranial nicotine self-administration at high doses. Lentiviral vector-induced re-expression of the β4 subunit into either the MHb or IPN restored a "stop" signal on nicotine self-administration. These results suggest that β4*nAChRs provide a promising novel drug target for smoking cessation.

Vatican City, May 8, 2020 / 04:00 am (CNA).- We must learn to let ourselves be consoled by Jesus when we are suffering, Pope Francis said at his morning Mass Friday.

In his homily in the chapel at Casa Santa Marta, May 8, the pope noted it was difficult to accept Christ’s consolation in times of distress. 

Reflecting on the day's Gospel reading, John 14:1-6, which records Jesus’ words to his disciples at the Last Supper, the pope said the Lord recognizes their sadness and seeks to console them.

"It is not easy to allow ourselves to be consoled by the Lord,” he said. “Many times, in bad moments, we are angry with the Lord and we do not let Him come and speak to us like this, with this sweetness, with this closeness, with this meekness, with this truth and with this hope.”

He noted that Jesus’ way of consoling was quite different to telegrams of condolence, which are too formal to console anyone. 

“In this passage of the Gospel we see that the Lord consoles us always in closeness, with the truth and in hope,” he said. “These are the three marks of the Lord's consolation.”

The pope observed that Jesus is always close to us in times of sorrow.

“The Lord consoles in closeness. And He does not use empty words, on the contrary: He prefers silence,” he said, according to a transcript by Vatican News.

He added that Jesus does not offer false comfort:  

“Jesus is true. He doesn't say formal things that are lies: ‘No, don’t worry, everything will pass, nothing will happen, it will pass, things will pass…’ No, it won’t. He is telling the truth. He doesn’t hide the truth.”

The pope explained that Jesus’ consolation always brings hope. 

He said: “He will come and take us by the hand and carry us. He does not say: ‘No, you will not suffer: it is nothing…’ No. He says the truth: ‘I am close to you, this is the truth: it is a bad time, of danger, of death. But do not let your heart be troubled, remain in that peace, that peace which is the basis of all consolation, because I will come and by the hand I will take you where I will be’.”

The pope concluded: “We ask for the grace to learn to let ourselves be consoled by the Lord. The Lord's consolation is true, not deceiving. It is not anesthesia, no. But it is near, it is true and it opens the doors of hope to us.”

After Mass, the pope presided at adoration and benediction of the Blessed Sacrament, before leading those watching via livestream in an act of spiritual communion.

The congregation then sang the Easter Marian antiphon “Regina caeli.”

At the start of Mass, the pope noted that World Red Cross and Red Crescent Day falls on May 8, the anniversary of the birth of Henry Dunant, founder of the International Committee of the Red Cross.  

Pope Francis said: “We pray for the people who work in these worthy institutions: may the Lord bless their work which does so much good.”

One of the loveliest towns in Italy is the walled city of San Gimignano, an hour’s drive from Florence. When I first visited it was bleak midwinter and all but a few shops and cafes were shuttered against the sleet. Its claim to fame is a profusion of medieval towers, hence its hyperbolic label as the Manhattan of Tuscany. When I arrived these fortresses soared overhead, making shadowy streets even darker.

The extent to which young adults' laboratory-confirmed sexually transmitted disease results and self-reported sexual behaviors are consistent has not been assessed in a nationally representative sample.

The primary purpose of this study was to determine whether young adults' reports of recent sexual behavior (presence of penile/vaginal sex in the previous 12 months) correspond with the presence of laboratory-confirmed nonviral STDs assessed by nucleic acid amplification testing.

Pediatric weight gain is a critical aspect of the obesity epidemic. Chronic stress produces physiologic perturbations capable of altering brain mechanisms related to eating as well as those implicated in self-regulatory behaviors.

We show that early childhood risk exposures are associated with weight gain in adolescence, independent of childhood BMI. We also find that deficiencies in self-regulatory processes help explain the link between chronic stress and adiposity. (Read the full article)

General measures discourage all self-referrals to the emergency department. For adults, self-referral to the emergency department has been associated with nonsevere disease, whereas severity of illness of self-referred children is still unknown.

One in four parents properly judged and acted on their febrile child’s illness by presentation to the emergency department on their own initiative. Measures to discourage parents from self-referral may potentially result in delayed or missed diagnoses. (Read the full article)

Nonadherence to antiretroviral therapy among children and youth with HIV is a frequent problem that can result in treatment failure and disease progression for this population. Children and adolescents face different barriers to adherence than adults infected with HIV.

Few studies have examined specific barriers to adherence as reported by children with perinatally acquired HIV and their caregivers. This report examines the agreement between child and caregiver perceptions of adherence barriers and the factors associated with these barriers. (Read the full article)

The relationship between energy intake and obesity in children has yielded inconsistent results. Efforts to improve dietary intake as a means of improving weight status have largely yielded disappointing results.

Self-reported energy intake for younger, but not older, overweight/obese children is higher than healthy-weight peers. In early childhood, higher (or excessive) energy intake may lead to onset of obesity, but other mechanisms may be important to maintain obesity through adolescence. (Read the full article)
